🚀 Release Notes (v3.0.0)
PDF Dark Mode Reader v3.0.0 — Major Update

We are excited to announce version 3.0.0 of PDF Dark Mode Reader! This major release transforms the extension into a fully-featured, premium PDF reading experience while retaining our strict 100% offline, privacy-first architecture.

✨ New Features

1. HD Rendering Engine

Retina/High-DPI Support: The underlying PDF rendering engine now respects your monitor's pixel density. PDFs and sidebar thumbnails render in crystal-clear HD on high-resolution displays.
Zero Memory Bloat: A rewritten rendering pipeline completely eliminates memory leaks by explicitly cleaning up internal font/image caches when pages are scrolled out of view.
2. Smart Bookmarks & Table of Contents

Bookmark Current Page (Ctrl+D): Save your exact spot in any document with a single click.
Persistent State: The extension uses a SHA-256 hash of the PDF to remember your bookmarks, zoom level, current page, and theme preference for every individual document you read across sessions.
Interactive Outline: If your PDF contains a built-in Table of Contents, it is automatically extracted and displayed in the sidebar for one-click navigation.
3. Productivity & Focus Tools

Focus Mode (F): Dim all UI elements and toolbars with a single click to immerse yourself entirely in the document.
Read Aloud / Text-to-Speech (T): An integrated TTS engine reads the text on the page out loud, perfect for accessibility or multitasking.
Reading Progress Bar: A sleek progress bar at the top of the screen visually tracks how far along you are in the document.
4. Premium Aesthetic Upgrades

New Iconography: A brand new transparent moon logo that looks stunning in the browser toolbar.
Refined Toolbar: The navigation toolbar has been rewritten using flexible layouts, preventing overlapping buttons and providing a modern, glassmorphic feel.
Upgraded UI Assets: Replaced legacy monochrome icons with modern, gradient-infused SVG assets.
🛠 Core Features (Always Included)

Multi-Theme Support: Choose from Classic Dark, Warm Dark (Claude), Blue Dark, Green Dark, Sepia, or High Contrast.
100% Local Processing: No accounts, no cloud sync, no tracking. Your files never leave your device.
Native Keyboard Shortcuts: Full support for keyboard navigation (arrows, J/K scrolling, zoom shortcuts).
Cross-Browser Manifest: Fully compatible with both Chrome (Manifest V3 Service Workers) and Firefox.

This update brings one of our most highly requested features to make navigating large documents easier than ever, alongside some under-the-hood performance trimming.

✨ New Features & Improvements:

Interactive Table of Contents: You can now navigate PDFs using their built-in bookmarks! The new Outline sidebar automatically extracts and displays the document's structure for rapid chapter-hopping.
Tabbed Sidebar Navigation: We've introduced a sleek new tabbed interface to the sidebar. You can now seamlessly toggle between the classic Thumbnails view and the new Outline view.
Keyboard Shortcuts: Power users can now instantly toggle the Outline sidebar by pressing Ctrl+Shift+O (Cmd+Shift+O on Mac).
Uncluttered Aesthetics: We kept the new outline clean. Page numbers for chapters stay hidden until you hover over them, ensuring the interface remains minimalist and distraction-free.
