Modular YouTube toolkit with Discovery, Quality, Focus mode, and Looper. Transform your YouTube experience from a clean, modular sidebar. Vivies Toolkit for Youtube combines five sidebar sections in this order: Discovery, Quality, Focus, Looper, and Settings. 🌟 KEY FEATURES Discovery: Replaces the default YouTube Home recommendation grid with a customizable discovery feed (world/country + category filters). Quality: Automatically applies your preferred playback quality and optional player size behavior. Focus: Lets you hide distractions like related videos, comments, Shorts blocks, notifications, and other optional UI sections. Looper: Adds a native-style Loop button on watch pages and a dual-range loop panel to repeat only the selected start/end interval. Settings: Toggle modules on/off, manage theme and language preferences, and control module-specific defaults. Per-Video Loop Memory: Saves loop start/end and enabled state per video in local Chrome storage. YouTube + YouTube Music Support: Looper behavior also runs on music.youtube.com. 💡 HOW TO USE Install the extension. Open YouTube (or YouTube Music) in your browser. Click the extension icon to open the sidebar. Navigate in this order: Discovery → Quality → Focus → Looper → Settings. Enable only the modules you want and adjust each module’s options from its panel. 🔒 PRIVACY & SECURITY Vivies Toolkit for Youtube runs primarily in your browser. Preferences and module state are stored locally using Chrome storage APIs. No advertising SDKs or third-party analytics are bundled in the extension. For Discovery feed functionality, the extension sends category/country request parameters to its configured Firebase Cloud Function endpoint to fetch YouTube trending data. The extension communicates only with required domains for its functionality: YouTube, YouTube Music, and the configured Vivies Firebase Function endpoint. ⚠️ DISCLAIMER Vivies Toolkit for Youtube is not affiliated with, endorsed by, or sponsored by YouTube or Google LLC.
