Links to headings now work inside the document: a table of contents written as [Install](#install) scrolls to that heading, using the same heading ids as GitHub. The Contents sidebar can list every heading or stop at H2, H3 or H4. Right-click the sidebar, or use Settings > General. Fixes: an escaped pipe (\|) in a table cell stays in that cell, as on GitHub, and a closing ## after a heading is no longer shown.

NEW IN 1.13 • Select text inside tables: a word, a whole cell (triple-click) or any range of cells. One cell copies as plain text, several cells as tab-separated values • Reload (Cmd+R, View > Reload, or the reload button): re-read the document from disk on demand. Contributed by a QuickMD user • Opening a file in full screen or Split View adds a tab in place. Contributed by a QuickMD user • Table headers are semibold • A heading's copy-section button sits right after the heading text again SOURCE EDIT (1.12) • Fix the Markdown you are reading without leaving the window: Option+Cmd+E, the pencil button, or File > Edit Source switch to the raw source at the line you are reading. A word you selected is already selected in the source • Cmd+S saves, Esc returns to the rendered view at the place you edited • Saves are byte-faithful: the file keeps its encoding, line endings, permissions and Finder tags - only what you typed changes • Unsaved text is never lost silently: closing a tab, a window or the app asks first • Requested by QuickMD users; thank you! FIXED • Search inside tables counts only what the table shows, and highlights no longer shift after letters such as the Turkish dotted I • Auto-reload recovers when a file that disappeared comes back at the same path (for example after a git checkout)

SELECT ACROSS THE WHOLE DOCUMENT • Drag from one block into the next - paragraphs, headings, lists, quotes, code, tables - and the view scrolls with you; Shift-click extends, double- and triple-click select a word or a paragraph • Cmd+A selects everything, Cmd+C copies exactly what is highlighted: clean text, tables as tab-separated values, math as LaTeX, no theme colours when pasted into Mail or Pages • Every copy shows a small note with the number of characters and words copied • New Settings > General: copy selected text automatically (off by default) • Requested by a QuickMD user (issue #33); thank you! IMAGES • Embedded images (base64 data, including SVG) render like any other image, on screen and in PDF; a placeholder never shows the encoded data. Reported by a QuickMD user (issue #32); thank you! • HTML img tags render as images, including the centered logo and screenshot blocks used in GitHub READMEs; width is honoured • Small images and badges keep their own size instead of being blown up; large ones still fit the column • PDF export and print now include images referenced by a relative path • Remote images load faster when you scroll back, and remote SVG badges render EDITOR HANDOFF • Cmd+E opens the document in Visual Studio Code, BBEdit, TextMate or Nova at the line you are reading; other editors open the file as before FIXED • Image and link syntax follows CommonMark: titles, paths with spaces, several images on one line, reference-style images and link-wrapped badges

GRAPHICS THAT FOLLOW THE TEXT • Images, image captions and Mermaid diagrams now scale with Cmd+ / Cmd-, keep their aspect ratio and stay inside the column; a graphic fitted to a narrow window also shrinks when the text gets smaller • Click any image or diagram to open it in a window-filling preview; Escape or Done brings the document back, and the diagram preview keeps its pinch and button zoom • Both contributed by a QuickMD user (issue #28, pull request #29); thank you! INLINE SVG • Fenced svg code blocks render as images, decoded natively by macOS (no web view, no bundled libraries, scripts in the markup are ignored). They scale with the zoom at their declared size, open in the preview on click and print / export to PDF as vectors. Markup that does not decode shows a notice; in PDF it appears as a code block ORDERED LISTS • The items of one list now share a single text edge: markers are right-aligned under the widest one ("9." under "10."), so item text starts at the same place on the first line and on wrapped lines alike; blank lines and nested content between items no longer split the list. Contributed by a QuickMD user (pull request #27); thank you! FIXED • A Mermaid diagram that first rendered below the fold could keep an oversized row REMOVED • The 1.8.0 layout fallback kept for one release after the 1.9.0 native layout; the native virtualized list is now the only document layout

SIDEBARS • The Table of Contents and Recent Documents sidebars can now be closed right from their headers (Cmd+Shift+T and Cmd+Shift+D still toggle them) MENUS • Table of Contents and Recent Documents moved from the Edit menu to View, next to Zoom and Reading Mode; shortcuts unchanged

USTOM FONTS • Settings gains a Fonts tab: choose any installed font family for body text and another for code (JetBrains Mono, Fira Code, a serif for long reads...) • Applies to every document, print and PDF export; font size and zoom are unaffected; the app's own controls keep the system font • Custom themes can bring their own typography with bodyFontFamily / codeFontFamily; a font that is not installed falls back to the system font • Requested by a QuickMD user (issue #18). Thank you! SOFT LINE BREAKS • A single newline inside a paragraph now reads as a space, exactly like CommonMark and GitHub, instead of a visible line break • Documents written one sentence per line flow as paragraphs; wrapped list items keep their hanging indent • Hard breaks still work: end a line with two spaces or a backslash • Contributed by a QuickMD user (pull request #19). Thank you! FIXED • A rare freeze while scrolling a document up and down with the mouse wheel

A community release: four of the seven changes arrived as pull requests from QuickMD users. Thank you! ZOOM • Cmd+ / Cmd- / Cmd+0 scales the whole rendered document, per window • Headings, body text, tables, code, math and footnotes all follow, search highlighting included • Every document opens at 100%; zooming one tab leaves the others alone GITHUB-FLAVORED ALERTS • [!NOTE], [!TIP], [!IMPORTANT], [!WARNING] and [!CAUTION] blockquotes render as colorful native callouts, exactly like on GitHub • Full text selection, search, zoom and PDF support BETTER PDF EXPORT • Vector text: sharp at any zoom, fully selectable and searchable, smaller files • Mermaid diagrams embed as rendered images instead of code blocks ALSO • New document windows remember the size you last used • Headerless tables (| | |) render correctly instead of disappearing • Wrapped list lines hang under the item text; nesting works for 2- and 4-space documents

COMPANION TO YOUR EDITOR • Auto-reload: QuickMD watches every open document and refreshes it the moment the file changes on disk. Enable auto-save in your editor and you get a practical live preview • Open in External Editor (Cmd+E): one-click handoff to your editor. First use asks which app to use; change it anytime in Settings -> Editor • Copy button on code blocks: hover and click BIG PERFORMANCE WIN • Documents with 10,000+ lines now open without freezing the UI thanks to native lazy text rendering • Native macOS text selection in paragraphs, quotes and code • Scrolling back to a Mermaid diagram is instant MERMAID • Zoom any diagram: hover, click the zoom button, then pinch or use the zoom controls • Fixed diagrams failing to render in files with Windows line endings ALSO FIXED • Windows (CRLF) files now render exactly like Mac/Linux files • YAML frontmatter renders as a tidy code block • Setext headings (text underlined with dashes) render correctly • "Copy section" no longer miscounts headings when code blocks contain # comments • PDF export no longer cuts off very long code blocks • Custom theme files with invalid colors show a clear error • Hardened how diagram content is passed to the renderer (security)

Version 1.5.0 — Custom Themes, Recent Documents, Native Tabs NEW • Custom Themes from Disk — drop a JSON file into the QuickMD Themes folder and it appears in the picker. Live reload, no app restart. Settings adds Import Theme, Open Themes Folder, and Reload buttons. Schema documented on GitHub with two starter palettes. • Recent Documents Sidebar (⇧⌘D) — see every document you've opened in this session. Click to re-open, drag the right edge to resize (160-500pt, persisted), hover any row to remove it. • Native macOS Tabs — every QuickMD document opens as a tab in one window. Switch with ⌘⇧→ / ⌘⇧← or drag tabs to reorder. IMPROVED • Code blocks now render through native NSTextView — cross-line text selection with auto-scroll-during-drag, like Xcode or Pages. • Per-tab keyboard shortcuts — ⌘F, ⌘⇧T, ⌘⇧D, ⌘⇧C now correctly target the active tab instead of every open tab. • Search input is debounced — no per-keystroke recompute when typing fast. • Loading indicator while parsing long documents. • Parser splits long bullet/link lists into smaller chunks for smoother rendering. Thank you to @cameronsjo for the custom themes feature request and to @COSMAX-JYP for the recent documents sidebar contribution!

New features: • LaTeX Math — display ($$...$$) and inline ($...$) math render with TeX-quality typography. Fractions, integrals, matrices, superscripts — all beautifully typeset. • Mermaid Diagrams — flowcharts, sequence diagrams, pie charts, class diagrams render directly from ```mermaid code blocks. • Footnotes — [^1] references render as superscript numbers with definitions listed at the end of the document. • All rendering works fully offline — no internet connection required.
