    Version 2.2.0 - The Smart Dashboard & Interactive Milestones Update

    What's New:
    1. Interactive Evaluation Milestones: Reaching your target view count (e.g., 5 views) now triggers a pulsating red dot on the sidebar. Inside the dashboard, you'll get two new quick-action buttons: "Subscribe & Remove" (🔔) or "Continue Evaluating" (🔄) to extend the trial by 3 more views.
    2. Smart Sidebar Progress Bar: The sidebar widget now features an ultra-thin, dynamic progress bar that calculates the average time left across all channels in your evaluation zone, turning red when time is running out.
    3. Enhanced Visual Dashboard: The "Last Played" tab now displays up to 5 of your most recently watched videos in a sleek, side-scrollable horizontal carousel. We've also added native creator logos next to channel names for faster recognition.
    4. Intelligent Sorting: Your evaluation list now automatically sorts itself based on remaining trial time, keeping channels with the most time at the top.
    5. Improved UI Legibility: Overhauled the typography and contrast in the toolbar popup for a much cleaner and readable experience, along with UI placeholders for upcoming individual channel timers (Pro).

    Version 2.1.1 - Major Stability, Performance & UI Overhaul

    What's New:
    1. Extended Local History: The "Last Played" tab now securely retains and displays up to the last 5 watched videos for any channel in your evaluation zone, complete with accurate title sync and high-quality native thumbnails.
    2. Sleek Dark UI Refresh: Refined the extension interface with fully synchronized rounded container structures (16px) and a solid dark-theme canvas to prevent visual clipping and eliminate white border artifacts in toolbar popups.
    3. Enhanced Performance Framework: Rewrote core event hooks using debounced MutationObservers (250ms delay) to dramatically reduce background CPU overhead, optimize battery consumption, and ensure fluid navigation on YouTube.
    4. Tiered Content Gate: Integrated a clean single-slot video preview mock within the 'New Videos' tray to gracefully outline premium upgrades and lock advanced tracking features behind Pro-tier indicators.

  • Version 2.0.0

    Released May 25, 2026 - 36.17 KB
    Works with firefox 142.0 and later
    Version 2.0.0 - Major Feature Update
    1. Automated Lifecycle & Background Expiry Engine (New background.js)
      Native Service Worker Alarms:Implemented a non-persistent background script (background.js) utilizing the chrome.alarms API to handle asynchronous time tracking.
      Silent Storage Purging: Engineered a periodic hourly task that runs safely in the background to evaluate stored creator timelines. It automatically evicts channels from the user's trial slots once their time limit expires, completely removing performance overhead from content scripts.
    2. Advanced In-Page Floating Panel Dashboard (UI/UX Upgrade)
      -Native Rail Overlay:Completely replaced basic browser alerts with a modern, high-end floating dashboard that slides out smoothly from YouTube’s native left navigation rail.
      -Global Click Interceptor: Implemented a safe click-away listener on the main window. If a user clicks anywhere outside the control panel, the dashboard automatically fades out and cleans itself up to ensure a distraction-free layout.
      -Event Bubbling Protection: Added strict isolation controls (stopPropagation) on the navigation controls and inner links inside the dashboard panel, ensuring structural actions don't accidentally collapse the interface.
    3. Deep Playback History Analytics & Tabs Framework
    4. Persistent Local Context Syncing: Expanded the local storage schema to track user behaviors. The extension now safely updates and persists metrics like lastPlayedId, lastPlayedTitle, and execution timestamps whenever a trial creation event triggers.
    5. Dynamic Popup Navigation: Refactored the internal structure of popup.html into a sleek, clean dual-tab system:
    6. "Last Played" Tab: Dynamically pulls the user's latest watched trial content from local storage and displays it as a clean clickable card, allowing instant direct navigation back to the video.
    7. "New Videos" Tab: Integrated a placeholder layout structure designed to support dynamic premium RSS feed updates in future milestones.
    8. Extended Discovery Guard (Home Grid & Search Syncing)
    9. Multi-Surface Content Script Tracking Shifted mutations far beyond the active video player view. The logic now actively hooks into elements across the native YouTube Grid layout (Home page /) and multi-card lists (Search results /results).
    10. Real-Time Context Badging:If a channel currently stored in the user's local evaluation slots appears in the Home feed or Search listings, the script instantly injects a sleek, native-looking "🟢 Evaluating" badge right next to the channel name to maximize visual awareness safely.
    11. Premium UI Branding & Sidebar Alignment
      -Unified Product Rebranding: Dropped all legacy experimental titles. Refactored the core interfaces, labels, and popups to reflect the official branding: "I May Subscribe".
      Aesthetic Circular indicator:Replaced the heavy, sharp green block marker in YouTube’s sidebar.
      Strict Single-Line Constraints:Applied defensive CSS.

    Fixed an issue where the extension content script was not triggering on dynamic page transitions (SPA navigation) from the YouTube home page. Updated manifest matches to execute across the entire domain and added a path-specific check inside the script.
