    Scrollbar Customizer: Version 11.9 Feature Highlights

    🎨 Enhanced Visuals & Presets

    • Streamlined Presets: Expanded to a single row of 10 narrow quick-select presets, including new Neon Pink, Cyan, Red, Orange, and Green options.
    • Real-Time UI: Every adjustment—from color swatches to numeric widths—now applies to the page instantly for a "live preview" experience.

    🏷️ Tab Color-Coding (Favicon Matcher)

    • Favicon Backgrounds: Added a "Match Favicon Background" feature that paints a solid square of your "Outline Color" behind the site icon. This is handy for color coding groups of tabs on the same site.
    • The "Guard Dog" Observer: Implemented a Mutation Observer that prevents dynamic sites (like Suno) from overwriting your custom tab color.
    • Smart Sizing: Icons are slightly inset (28x28) within the colored background to ensure a visible border even on perfectly square site icons.
    • CORS Safety: Includes a fallback mechanism that uses a solid color square if a site's security policy blocks access to the original icon.

    ⚙️ Advanced Logic & UI Controls

    • Three-Button Action Row: Replaced the old save button with:
      • Save: Commits changes to your global Greasemonkey storage.
      • Undo: Instantly reverts the page to your last saved configuration.
      • Exit: Closes the menu while keeping your current tweaks active for that specific tab session.
    • Top-Right Exit: Added a bold "✕" button for a quick, session-preserving close.
    • Layout Integrity: Optimized CSS selectors to target the html root and removed display-forcing rules that previously caused layout breakage on responsive sites.
    • Conditional Sync: Unchecking "Enable Custom Scrollbar" now automatically disables favicon matching for a cleaner reset.
  • v11.1 2026-02-03
