v1.4.1 — Inline Math, Footnotes, Homebrew

What's New

Added

• Inline Math: $...$ expressions render as TeX-quality graphics inline with paragraph text — fractions, integrals, superscripts all render beautifully within a sentence
• Footnotes: [^id] references render as superscript numbers, definitions listed at end of document
• Homebrew Cask: brew install --cask quickmd formula included

v1.4.0 — LaTeX Math & Mermaid Diagrams

What's New

Added

• LaTeX Math Rendering: Display math blocks ($$...$$) are now rendered with TeX-quality typography. Supports fractions, integrals, matrices, sums, and all standard LaTeX notation. Powered by vendored SwiftMath — native Core Graphics rendering, zero network dependency.
• Mermaid Diagram Rendering: Fenced code blocks with ```mermaid are now rendered as visual diagrams — flowcharts, sequence diagrams, pie charts, class diagrams, and more. Powered by bundled Mermaid.js.

Fixed

• Dead App Store Link: Updated the Mac App Store link to the correct app ID.

---

Zero external dependencies. SwiftMath is vendored (copied into the project), Mermaid.js is bundled as a static resource. No SPM packages, no CocoaPods, no network required.

v1.3.3 — Local Image Access, Persistent ToC, Scroll Fix

What's New

Added

• Folder Access for Local Images: QuickMD now prompts for folder access when a local image can't be loaded due to sandbox restrictions. Access is persisted via Security-Scoped Bookmarks — the prompt only appears once per folder.
• Persistent Table of Contents: The ToC sidebar state now persists across app launches and new documents.
• Check for Updates: GitHub version now shows "Check for Updates" in the Help menu, with a subtle notification when a new version is available.

Fixed

• Scroll Freeze on Complex Code Blocks: Fixed a UI freeze caused by rapidly creating/destroying views containing box-drawing Unicode characters during fast scrolling.
• Cmd+W to Close: Restored the standard macOS Close Window shortcut that was accidentally removed by a CommandGroup override.

v1.3.2 — File > Open, Local Link Navigation, URL Encoding

What's New

Added

• Local Markdown Navigation: Clicking a link to another local .md, .markdown, .mdown, or .mkd file now automatically opens it in a new QuickMD window, bypassing default system editors.
• Space Character URL Parsing: Links with spaces in paths/titles are now correctly percent-encoded and activate properly.

Fixed

• File > Open Menu: Restored the native File > Open and File > Open Recent menu items that were previously hidden.
• Relative Document Links: Relative links like ./other.md are now resolved against the originating document's directory.

v1.3.1 — Copy to Clipboard & Search Improvements

What's New

Copy to Clipboard

• ⌘⇧C copies the entire raw markdown to clipboard
• "Copy source" button (top-right) — hover to reveal, click to copy whole file
• Copy sections — hover any heading in the main content or ToC sidebar to reveal a copy icon that copies that section's markdown
• Toast feedback — "Copied!" notification on all copy operations

Search Improvements

• Word-level highlighting now works inside code blocks, tables, and blockquotes (previously only text and headings)
• Per-occurrence navigation — arrow keys move between individual word matches, not just blocks. Counter shows exact count (e.g., "5/19")
• Focused match highlighted in orange, all others in yellow

Performance Fixes

• Critical hang fix: MarkdownBlock converted from enum with computed id to struct with stored id — eliminates thousands of AttributedString copies per LazyVStack layout pass that caused 100% CPU freezes during scrolling
• Search navigation: Pre-computed highlight cache + dedicated focus state. Arrow clicks now recompute only 1 block instead of all visible blocks
• Optimized searchHighlight: Single-pass parallel index iteration replaces per-character dictionary allocation
