What's new
Export — PDF, DOCX, HTML
* Export to PDF via the browser's native print dialog, with the active theme preserved in the output (10 themes, 3 rendering modes, 6 font schemes)
* Export to DOCX — editable Word document with nested formatting, lists, task list checkboxes, Mermaid diagrams, blockquotes, tables, and syntax-highlighted code
* Export to HTML — self-contained web page with inlined CSS and optional embedded fonts
* On sandboxed pages (e.g. raw.githubusercontent.com), the PDF tile is dimmed with a tooltip pointing to Cmd/Ctrl+P, and DOCX/HTML downloads route through the background

Presentation Mode
* Full-screen slideshow from any rendered markdown document — one click in the action strip
* Slides split on --- horizontal rules (Pandoc/Marp convention); falls back to H1/H2 headings for unstructured documents
* Keyboard navigation: arrows (next/prev slides), up/down (scroll within a slide), Home/End, Space, Escape
* Auto-fading progress bar + slide counter at the bottom
* Font and content width scaled up for audience legibility
* Code blocks wrap instead of horizontal scroll so they don't keyboard-trap

Read Mode improvements: Font and content width now scale by 1.3x from the user's settings for comfortable long-form reading

TOC sidebar
* Reading-progress footer is now pinned (sticky) while the link list scrolls
* Drag-to-resize handle on the left edge, 220–480 px bounds, persisted across sessions

"Render this page" button: Now works on pages without a .md extension (e.g. bare LICENSE files on raw.githubusercontent.com)

Firefox compatibility
* Fixed rendering on Firefox's text viewer (different DOM structure from Chrome)
* Fixed auto-reload polling on local file:// URLs in Firefox
* Fixed theme-watcher cleanup after extension reload

12-language support (new)
* Full internationalization with 12 languages: English, Spanish, French, German, Portuguese (PT and BR), Japanese, Chinese (Simplified), Korean, Italian, Russian, and Arabic (with RTL support)
* All UI strings, tooltips, settings panel, export dialog, and accessibility labels are localized
* Extension name and store description are localized across all 12 languages

v0.11.1 — Hotfix
- Fix: extension no longer interferes with legitimate websites that have .md in their URL
- Fix: removed broad wildcard URL matches that broke non-.md raw file pages
- Fix: pages hidden by anti-flicker CSS are now restored when MarkLens decides not to render

New features:
- Read mode: distraction-free fullscreen with prev/next file navigation
- Copy buttons on H1/H2 headings (copy as HTML or markdown)
- Document-level copy buttons in toolbar (HTML + MD)
- Right-click to copy file/folder path in tree sidebar
- Segmented Preview/Raw toggle (replaces old Raw button)
- Smart folder picker: only reuses saved folder if current file is inside it

Fixes:
- Raw view shows correct file after switching via folder tree
- Raw view bottom padding for action dock visibility

v0.9.0 — Phase 1.5: Daily-Driver Update

New features:
• Auto-render markdown on GitHub, GitLab, and Bitbucket raw file URLs

• "Render this page" button — render markdown on any page via popup
• Export/import settings as JSON (copy to/paste from clipboard)
• Named style profiles — save and switch between multiple setups

Improvements:
• Document rendering mode redesigned with Word-like heading bands

• ToC heading scroll offset — headings no longer hidden behind toolbar
• Consistent sidebar font sizing

New permissions:
