Changelog

The settings panel can now customize the title-bar format (file name or full path), and the font panel shows the font currently in use.

A Rendering Engines manager joins the settings panel: view, download, or delete the syntax-highlighting, Mermaid, and math engines at any time; the engine download prompt now supports "don't show again".

Launching by double-clicking a .md file no longer silently changes your system's default open-with app — it binds only when you click "Set as default" yourself, and the welcome page clearly shows the unbound state.

Read state of feedback replies is now stored in the cloud — a reply you've already seen won't pop up again after switching computers or reinstalling.

Mapped drives and network shares no longer show the \\?\UNC\… prefix, and Ctrl+E external-editor sync now works on those paths too.

Shortcut keys now come with preset schemes you can switch in one click, and nearly every action can be rebound to any key you like.

A new Files tab in the sidebar browses every Markdown file in the same folder like a file explorer; clicking a file switches instantly with no flicker and no full reload.

A word-count badge in the bottom-right corner shows live document and selection counts; toggle it in the settings panel (off by default).

Slimmer right-click menu: font and zoom entries removed, a direct Layout Settings entry added, and the mind map moved into the Export submenu.

Fixed window-position memory across multiple monitors — a window closed on a secondary display now reopens on that display, in place.

Fixed a freeze when searching for very short terms with Ctrl+F, and fixed relative-path file links leaving the whole page unresponsive after a click.

Fixed PDFs exported under the dark theme showing a black border.

A pipe | inside a list item is no longer mistaken for a table, so nested lists render correctly.

Custom app icon: replace the window and taskbar icons — and even the .md file icon in Explorer — with your own.

Live-preview plugins for Sublime Text and VS Code (Pro): the preview refreshes as you type, with two-way cursor and selection sync.

Mermaid diagrams can be edited visually in F2 edit mode: double-click to change text, click to change shapes, drag to connect nodes — changes write back to the source automatically.

==highlight== syntax is now supported, rendered as a distinct yellow marker adapted to both light and dark themes.

Hover a Mermaid diagram or image for the ⛶ fullscreen badge and click to view it full screen; Mermaid diagrams stay vector-crisp at any zoom level.

Tables gain zebra striping, and a visual color editor lets you tune 11 common colors with a picker and save instantly — configured separately for light and dark themes.

Fixed PDF export doing nothing on macOS (it now opens the system print panel, where you can save as PDF); the feedback window no longer vanishes on focus loss, so drafts survive.

The welcome page is redesigned: opening a file and drag-and-drop .md preview front and center; settings moved into an in-page dialog, retiring the standalone settings window.

One-click expand/collapse in the TOC: hover an H1 row for the expand and collapse icons, applied only to that section's subtree — ideal for focusing on one chapter in long documents.

The payment page now accepts invite codes — enter one and the discounted price and payment code update automatically.

Fixed images referenced with ../ relative paths failing to display.

Fixed multi-line HTML comments in a document swallowing the page UI, leaving the title bar gone and the window unresponsive.

Mind-map fullscreen view (Pro): right-click "View as mind map" and the whole document becomes an interactive mind map — headings as branches, lists as leaves; scroll to zoom, drag to pan, click to collapse, following the light/dark theme.

Custom color CSS: edit custom.css next to your config for hot-reloaded theming with no restart; reachable straight from the settings panel.

After you edit and save in an external editor, the reading page refreshes seamlessly in place — scroll position stays put and only the changed content updates.

Native traffic-light buttons join the macOS title bar, which now follows the dark theme; settings rows are clickable across their full width for easier toggling.

In F3 split editing, selecting text in the preview pane automatically selects the matching source in the editor — handy for copying or rewording.

The TOC font size is now adjustable instead of fixed at the default.

Preview refreshes are now partial: only the changed blocks re-render on edit or save, keeping scroll position and untouched content in place with visibly less flicker.

Fixed find results in F3 split view drifting out of sync with the source pane; the find state now recovers on its own.

Printed output is now always rendered in light colors — dark backgrounds no longer waste ink.

Fixed the settings panel staying hidden when re-entering F3 split editing.

Printing from the right-click menu no longer forces a light theme: dark themes print exactly as shown with backgrounds preserved, and the print dialog itself now follows the app's light/dark setting.

Fixed .md links whose target file names contain Chinese or other special characters falsely reporting "link target not found".

Reading positions no longer leak across documents when you follow an .md link and come back — each document's remembered scroll position stays its own.

The device ID is now click-to-copy in the About dialog and the welcome page footer, with a confirmation toast — handy when reporting issues.

macOS now runs all document windows in a single process with one Dock icon, plus a Window menu (⌘W close, ⌘M minimize).

Switching from the Microsoft Store version to the installer/portable version no longer loses anything: your settings and downloaded engines (syntax highlighting, Mermaid, math) are migrated automatically on the next launch — no re-downloads, no reset preferences.

The device ID is now always visible in the About dialog and on the welcome page footer — no more double-clicking the version number to find it.

Fixed F3 split-view editing breaking its layout after maximizing or restoring the window: the editor pane width now reflows with the window, and custom ratios set by dragging the divider scale along with it.

In F2 Live Edit, typing ``` or ```python then Enter renders the code block immediately, with the cursor placed inside it — no stray blank lines.

Right-click menu gains Copy and Select All — after selecting text, the copy you instinctively reach for is right there.

Fixed lines starting with 4+ spaces inside fenced code blocks being incorrectly split into separate blocks.

Fixed selecting all text inside a single block and pressing Delete doing nothing in F2 Live Edit.

Code block toolbar: line-number / wrap icons redrawn as crisp vectors, active states no longer turn blue, and the language label is now precisely centered against the icons.

Table fullscreen viewer: hover a table and click the ⛶ badge to open it full-screen — laid out at natural width without wrapping, horizontally scrollable, resizable by dragging the corner, movable by its header; Esc to exit.

One-click CSV export for tables from the column context menu or the fullscreen viewer — UTF-8 with BOM, opens cleanly in Excel.

New corner-style setting (rounded / sharp) in the Settings panel: one switch covers code blocks, tables, math, Mermaid cards, and exported HTML; the choice is remembered.

In F2 table editing, grab a column handle and drag to move the whole column, with the drop target highlighted live.

PDF export overhaul: follows your current color scheme, keeps backgrounds intact (dark themes no longer export as white), drops the header/footer, and eliminates the blank trailing page.

F2 Live Edit now supports cross-block copy/cut/paste with formatting: selections spanning paragraphs, tables, or code blocks paste as proper Markdown, and cross-block delete works in one keystroke — undoable.

Exported single-file HTML now supports collapsible H1–H3 headings, matching in-app behavior.

Outline panel polish: compact tabs and a smooth top fade-out while scrolling.

A new Print command in the right-click menu sends the rendered page straight to the system print dialog — a separate path from Export to PDF.

Fixed a double separator line appearing in the right-click menu when some entries are hidden.

The document body and the floating outline panel always keep 20px of breathing room — the text no longer touches the panel edge at full column width or narrow windows.

Admin reply alerts are now a corner notification card instead of a blocking centered dialog: replies slide in at the top-right as soon as they arrive, and also appear when you open the next document. Click "Got it" and it never bothers you again.

Exported HTML now strictly follows your currently active theme and color scheme — fixed exports being stuck on an old baked-in scheme, so what you export now matches what you see on screen.

All dialogs (About, Feedback, Fonts, Sponsor, and more) now follow the active color scheme, and UI elements like floating buttons, cards, and the zoom indicator react instantly when the system switches between light and dark — no restart needed.

Settings panel redesigned: clearer sections with spacing, dividers, and bold headings; clicking a menu item scrolls smoothly to its section; and the panel can be dragged by its header.

Export to PDF on Windows now uses a native pipeline: a system save dialog produces the PDF directly, with the date and document name in the header and 1/N page numbers in the footer. It also works around a WebView2 bug where "Save as PDF" from the print dialog could produce an empty file.

Single-clicking the title bar no longer restores the window by accident — only a double-click toggles maximize/restore.

Dragging the title bar while maximized now restores the window and keeps it under the cursor as you drag, matching native title bar behavior.

Heading folding: hover to the left of an H1–H3 heading to reveal a ▸/▾ toggle, then click to collapse or expand the whole section. Works in both preview and F2 live edit, making long documents easier to navigate.

Real undo/redo (Ctrl+Z / Ctrl+Y) in F2/F3 editing — edits can be rolled back step by step instead of starting a whole section over.

In-app feedback now supports attachments — up to 3 images or files, so screenshots and logs come along for the ride. You'll also get an in-app popup when the developer replies, no need to check the website.

Line numbers and word wrap are now controlled per code block, with an always-visible horizontal scrollbar and language tag; you can also set both as global defaults in the settings panel.

F3 split view can swap left/right panes from the context menu; editing shortcuts are now consistent across platforms, with a shortcut cheat sheet available from the menu.

Export to PDF / printing no longer suggests "127.0.0.1" as the file name or shows it in the header — the document name is used instead.

A ⚙ button in the title bar opens a brand-new settings panel: theme, color scheme, font size, column width, and spacing controls, customizable F2/F3/F4 shortcuts, the single-Enter line break toggle, and feedback — all in one place.

Fixed inflated Ctrl+F match counts (script source and hidden math copies were being counted), and wide tables overflowing the content column — cell content can now wrap anywhere.

Three-way theme choice: Follow System (default) / Light / Dark, switchable from the right-click menu and remembered.

F2 live edit gets a floating format toolbar with bold, italic, link, and more at your fingertips — dismissible and remembered.

History and Favorites are back, each individually toggleable from the settings panel; turn both off for a pure outline view.

F3 split editing can swap panes left/right via a toolbar ⇄ button (preference remembered); exiting edit mode no longer jumps, and theme/color sync issues are fixed.

Windows and macOS now use a custom theme-aware title bar. Colors follow the active light/dark theme and color scheme; Windows keeps system shadows, snap layouts, and edge resizing, while macOS keeps the native window border, shadows, and edge resizing, with black-edge rendering fixed.

On macOS, double-clicking another .md file now opens it in a new window instead of replacing the document you're reading.

Fixed Mermaid pie, ER, journey, Git graph, and other diagram colors in dark mode, as well as invisible text and arrows when viewing sequence diagrams fullscreen.

Fixed exported HTML files where Mermaid diagrams could fail to render and scrollbars stayed permanently hidden. Exports are now lighter and use the same auto-hiding scrollbar behavior as the app.

The right-click menu adds "Export as Single-file HTML": images are embedded into one portable file that works offline while keeping the TOC, search, zoom, and current theme. Unlike PDF, long code blocks and wide diagrams remain scrollable, and copied code has no hard line breaks.

F2/F3 editing modes now support Tab snippets: type h1-h6, table, table2x3, code, python, link, line, or red to insert headings, tables, code blocks, links, dividers, or colored callouts. Live Edit immediately re-renders and focuses the inserted block.

Table row insertion now uses only Tab in the last cell, removing the floating strip below tables. The line-number toggle persists after edits, and split view scrolls to the bottom when needed.

Ctrl+F is unified across preview, F2 Live Edit, and F3 split editing: real-time highlighting, match count, previous/next navigation, and Esc to close. Search marks are never saved into the document.

The reading view is cleaner: scrollbars stay hidden by default, appear while scrolling or hovering a panel, then fade out when idle. The TOC toggle is also lighter and sits closer to the edge.

Added a portable Windows ZIP: extract and run with no registry writes, then delete the folder to uninstall. The new download center brings together the Windows installer, portable ZIP, Microsoft Store edition, macOS DMG, and Android APK.

Inserting a table between two tables now works at the source level: adjacent tables no longer merge accidentally, and entering/exiting edit mode no longer causes phantom-gap layout shifts. Hover the gap to insert content directly.

Table columns now support separate header and body alignment. Ctrl+B / Ctrl+I toggles bold or italic for the current word, Tab / Shift+Tab moves between cells, and Tab in the last cell adds a new row.

Fixed empty table cells collapsing row height and making cursor placement difficult.

Fixed macOS shortcuts including Cmd+C/V/X/Z/A, Cmd+S, and Cmd+B/I/U. Context-menu paste now uses the native action, avoiding repeated system permission prompts.

F2/F3 shortcuts and menu labels now show ⌘/⇧ on macOS, and the editor undo stack stays continuous instead of jumping back to an older state.

The GitHub theme is back based on user feedback, placed directly below Default.

Fixed .md files showing a blank-page icon in Explorer after being associated with mdview; the install and release pipeline now validates the icon as a fallback.

Removed the redundant "Contents" header so the outline starts at the top. History and Favorites were also removed while reading-position memory remains, returning the interface to its open-and-go focus.

The code-block toolbar is hidden until hover, with a redrawn line-number icon. Toggling line numbers no longer causes the page to shift.

Fixed copy, word-wrap, and line-number buttons becoming unresponsive after clicking a code block in F2 Live Edit.

Press F2 or F3 again to exit the current editing mode, just like Esc. Also fixed Windows WebView2 intercepting F3 before the page could handle it.

The About window now includes a feedback panel: submit bugs or suggestions and view developer replies without opening a web page. Device information is attached automatically.

Live Edit is more faithful: images and links can be edited as Markdown source when focused, exiting an untouched quote no longer rewrites the file, and Mermaid blocks are no longer mistaken for rich text.

When the About window finds a new version, Windows users can update in one click: mdview downloads the installer, verifies its SHA-256, installs silently, and relaunches automatically — no manual website download required.

Press F2 to edit right inside the preview: click any part of the text to modify it in place, just like in Word. Headings, lists, tables and code blocks re-render instantly, with auto-save, full undo/redo, and Esc to exit. The right-click menu adds formatting tools (bold / italic / strikethrough / link / table / callout); hovering a table lets you add or remove rows and columns, move it, or sort it.

Support for relative links between Markdown documents: click links like ./dir/x.md or ../y.md#anchor to open the target document in the current window and jump to the heading. Alt+← goes back to the previous document, so you can move between notes like in a browser.

F3 split-screen editing upgraded: edits save in real time and the preview refreshes seamlessly — change something on the left and the right updates instantly. Entering edit mode now jumps to your current reading position, and exiting no longer causes a flash.

Outline (TOC) now supports collapsing and expanding level by level: the outline of a long document no longer scrolls off the screen. Collapse state is remembered per document and restored on next open.

New line-number toggle at the top-right of code blocks: show or hide line numbers with one click. Line numbers are drawn by CSS, so copying code never carries them into the clipboard.

More details: long lines in code blocks can be toggled to word wrap; UI language gains a "Follow System" option; Alt+scroll in the gap between article and TOC now pans the whole view without changing the column width.

macOS edition launched: download and use on macOS 10.15+, with independent releases for each platform.

New "Single Newline as Break" toggle: by default a blank line is needed to start a new paragraph; enabling it makes a single newline break the line, matching how most online editors work. The menu item carries a ⏎ icon and shows the resulting state directly — one click to switch, auto-saved.

Built-in editor now supports direct pasting (Pro Edition): copy an image or file, press Ctrl+V, and it's automatically saved to a hidden assets folder next to the document with the matching Markdown syntax inserted at the cursor — no more manually creating folders or moving files around.

The editor gains a help button and a keyboard-shortcut cheat sheet, making common actions obvious at a glance; the TOC panel's close button also gets a clearer hover tooltip.

Color themes fully refreshed: 9 new themes — Glacier, Neon Violet, Mint, Lychee, Violet, Editorial, Forest, Sunset, and Typewriter — while 4 older themes were retired. More styles to choose from.

Footnotes automatically get a ↩ backlink, so you can jump back from the note at the bottom to where it's referenced in the text.

Fixed an issue where the right-click menu occasionally failed to open under the dark theme.

Automatic version check: a silent background check at startup, and the About window shows a prompt when a new version is available — no need to compare version numbers on the website yourself.

History entries can be deleted individually, or a whole day cleared in one click, so the history panel no longer grows endlessly.

Fixed an issue where $$ block math formulas failed to render in some documents (Pro Edition).

New split-pane built-in editor: edit Markdown on the left, live preview on the right, with scroll auto-aligned by section. Type table / link / img then press Tab to expand a snippet. Press F3 for the built-in editor and F4 for an external editor. The editing component is ~50KB, downloaded on first use and available offline afterwards.

Mermaid diagrams support double-click zoom: double-click an oversized flowchart or sequence diagram to enter a fullscreen viewer with scroll zooming, drag panning, and fit-to-window. Diagram colors were also refreshed to a cleaner blue palette that stays readable in both light and dark themes.

More ways to open files: Ctrl+O or the "Open File" menu to pick a document, or drag a .md straight into the window — both switch in the current window. Clicking a file in history / favorites no longer opens a new window either.

"Favorites" feedback feels more natural: after favoriting, a soft pulsing hint appears at the top of the favorites list instead of a flying-icon animation. Each entry can be removed on hover, and already-favorited files appear grayed out in the right-click menu.

Right-click menus are smoother: submenus expand on hover, and clicking a main item like "Edit" no longer accidentally closes the menu. Refreshing a document with the TOC collapsed no longer shows the expand-then-collapse animation.

Fixed an issue where Markdown table alignment syntax (:---, :---:, ---:) wasn't applied.

The outline panel gains three tabs — Contents / History / Favorites. History is grouped by day (Today / Yesterday / specific dates), giving a clear timeline just like Chrome's history.

The right-click menu adds "Favorite this file / Unfavorite" to pin frequently used documents into the Favorites tab, so even a large note collection stays one click away.

Each Markdown file opens in a single window: double-clicking it again just activates the existing window instead of stacking duplicates.

Every document remembers its reading position: reopen it and you're back where you left off. Refreshes triggered by saving in an external editor also resume automatically.

Title bar now shows the full document path instead of just the filename, so multiple notes with the same name can be told apart at a glance.

Right-click menu streamlined into three groups (Appearance / Edit & Export / About), keeping only the most common actions for a lighter, faster experience.

Menu colors now use CSS variables, automatically following dark/light theme switches — no more color mismatches.

About dialog is more restrained: usage count is hidden by default, double-click the version number to expand. The exe path is shown and copyable.

Added a three-dot menu in the top-right corner; previous right-click actions moved into the dropdown. The content area's right-click now restores the browser's native menu for less distraction while reading.

Table of Contents (TOC) can be toggled with one click for a more spacious reading area. Expand/collapse is merged into a single subtle toggle icon on the panel's right edge that follows the border when dragging to resize column width.

"Support Author," "Visit Website," and other entries moved from the bottom of the TOC into the top-right popup menu, making the interface more focused on content.

Welcome window redesigned to be cleaner and more refreshing. Version number now indicates the current edition (Community / Pro Trial / Pro).

Fixed an issue where Ctrl+E couldn't jump to the correct line when opening documents with Notepad++: the line number parameter wasn't concatenated as -n<line>, so Notepad++ treated it as a separate argument and always stayed at the first line.

Support for GBK/GB18030 encoded documents: many older documents on Windows use GBK encoding by default. Previously they'd show garbled text or errors — now they're automatically detected and previewed correctly.

"Color Theme" menu redesigned: 8 themes displayed as cards with instant hover preview and a more intuitive selection state.

Right-click menu adds "Color Themes": 8 built-in themes including RED (Xiaohongshu), Tech, Girl, Colorful, GitHub, Duolingo, Linear, and Notion. Click to preview instantly, auto-save on confirm — giving plain Markdown documents some color.

Pro Edition adds math formula rendering (KaTeX) with LaTeX syntax support. Rendering engine downloads on-demand and works offline.

Zoom now supports keyboard shortcuts: Ctrl+↑↓ for font size, Alt+↑↓ for column width.

Fixed an issue where the "Unlock Pro Edition" button in the outline area didn't respond to clicks.

Ctrl+E now supports EmEditor, auto-detecting the install path and jumping to the corresponding line.

Launching an external editor via Ctrl+E no longer pops up an unnecessary command-line black window.

Right-click menu adds body font selection, supporting all installed system fonts.

Font size and column width zoom are now separate: Ctrl+scroll for font size, Alt+scroll for column width.

Fixed an issue where in-document anchor links couldn't navigate.

Code block syntax highlighting. Downloads ~120KB rendering library on first use, then works offline.

Body text supports Ctrl+scroll for font size zoom with automatic column reflow.

Outline (TOC) unified as a full-height sidebar with four-position switching for smoother navigation.

Pro Edition trial changed to 100 free uses; click "Maybe Later" to continue after expiration.

Pro Edition launched (includes Mermaid diagrams).

Mermaid diagram rendering: flowcharts / sequence diagrams / Gantt charts. Rendering engine downloads on-demand and works offline.

Markdown parsing engine changed to static linking to resolve antivirus false positives.

WebView2 user data directory redirected to local path — no longer writes to system directories.

Double-click .md files to read instantly; auto-registers file association after installation.

Document outline (TOC) sidebar with auto-highlight of the current section on scroll.

Dark/Light theme toggle with auto-saved preferences.

One-click PDF export/print.

Select text and press Ctrl+E to auto-open editor and jump to the corresponding line.

Right-click menu integration: theme, outline, export, and other common actions.

Fixed an issue where .md files were still hijacked by VS Code and other editors after binding.
