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. Bug fixes: • Fixed scroll freeze on documents with complex Unicode characters • Restored ⌘W (Close Window) shortcu

Bug fixes and new features: • Local images now load properly — QuickMD prompts for folder access when needed (one-time per folder) • Table of Contents state persists across app launches • Fixed a scroll freeze on documents with complex code blocks • Restored ⌘W (Close Window) shortcut

Bug fixes and improvements: • Restored File > Open and File > Open Recent menus that were accidentally hidden • Links to other local Markdown files now open directly in QuickMD instead of the default system editor • Fixed links with spaces in filenames — they now open correctly • Fixed relative links (e.g. ./other.md) resolving against the document's folder

Search, Themes, Clipboard & Navigation Update NEW FEATURES • Find in document (Cmd+F) — search with per-word highlighting and navigation across all block types • Table of Contents sidebar (Cmd+Shift+T) — auto-generated from headings, click to navigate • Copy to clipboard (Cmd+Shift+C)— copy entire raw markdown with one shortcut • Copy sections — hover any heading to reveal a copy icon for that section • "Copy source" button in top-right corner • 7 color themes — Auto, Solarized Light/Dark, Dracula, GitHub, Gruvbox Dark, Nord • Theme picker in Settings (Cmd+,) with color previews • Nested blockquotes with level indicators • Reference-style links ([text][id]) per CommonMark spec IMPROVEMENTS • Word-level search highlighting in code blocks, tables, and blockquotes • Per-word match navigation — counter shows every occurrence, not just blocks • Focused match in orange, other matches in yellow • Per-block PDF export — no more mid-block page splits • Major performance improvements for scrolling and search navigation

Performance & Quality Release: • Faster document rendering with optimized caching • Improved syntax highlighting performance for code blocks • Reduced memory usage through smart resource management • Enhanced error handling for PDF export • Improved reliability across all features

Performance Optimizations This update focuses on speed and efficiency improvements: • Faster rendering - optimized view updates and layout • Lower memory usage - images are now downsampled for display • Smoother theme switching - stable identifiers prevent flicker • Better table performance - simplified layout calculations
