    What's New in Version 0.2.0
    
    UI & Experience Enhancements
    
    - We replaced the basic "Scroll" slider with a visual minimap. You can now see the entire video's waveform at a glance and click-and-drag the highlighted window to pan smoothly across the timeline.
    
    - Double-Click Shortcuts: Double-clicking the Zoom slider now automatically calculates the perfect zoom level and centers the screen on your active loop. Double-clicking the Speed slider instantly resets playback to 1x.
    
    - Touch Device Fixes: Swiping to draw loops on tablets and touchscreens will no longer accidentally trigger the browser's native "back/forward" page navigation.
    
    Bug Fixes & Stability
    
    - Audio/Video Freeze Fix: Resolved a critical issue where drawing a loop could permanently silence the audio or freeze the video due to browser Content Security Policy (CSP) blocks.
    
    - Endless Seeking Fix: Fixed a bug where loading a very short imported loop preset would cause the video player to get stuck in an endless seeking loop.
    
    - Background Stability: Handled "Extension context invalidated" errors that previously occurred when the browser updated the extension in the background.
    
    - Memory Management: Fixed memory leaks that could occur when navigating between different videos using YouTube's internal (SPA) routing.
    
    - Modernized Audio Engine: Replaced deprecated Web Audio API nodes with modern AudioWorklet nodes for faster, more stable zero-crossing detection.
