Extension Hub: All-in-One Micro-Extension Suite

A modular extension launcher featuring YouTube Music Switcher, Font Finder, Color Picker, and Website Dark Mode Forcer.

Extension Hub is an all-in-one productivity suite and modular extension manager. Instead of installing dozens of separate browser extensions that clutter your toolbar and slow down your browser, Extension Hub hosts a curated collection of high-performance micro-extensions inside a single lightweight popup. FEATURES • YouTube to YouTube Music Switcher - Timeline Switch Button: Injects a native YouTube Music switch icon directly into the YouTube video player controls. - Timestamp & Playlist Sync: Jump from any YouTube song or video to YouTube Music with preserved playback timestamps (&t=...s) and playlist context. - Shorts & Hotkey Support: Works on YouTube Shorts and supports Shift+M keyboard shortcut for instant audio switching. - Custom Settings: Choose navigation target (same tab or new tab), toggle auto-pause, and convert URLs instantly. • Font Finder Typography Inspector - Hover over any element to inspect rendered font family, font size, weight, line-height, letter-spacing, and colors. - Copy CSS rulesets and Tailwind CSS utility classes with one click. - Live editable preview box to test typography tweaks on the fly. • Pixel Color Picker & Palette Builder - Sample any pixel on your screen with precision using the native EyeDropper API. - Automatically copy HEX, RGB, and HSL values to clipboard. - Maintain a saved palette history for your design projects. • Smart Website Dark/Light Mode Forcer - Enforce clean, high-contrast dark or light mode on any website. - Intelligent media detection preserves photos, videos, canvas, and graphics without washed-out colors. - Multiple presets: High Contrast Dark, Soft Charcoal, Light Mode Invert, and Warm Night Shift. • CSS Style & Box Model Inspector - Click any DOM element to extract computed styles, box model dimensions (margin, padding, border), and Tailwind classes. • HTML to Figma Vector Importer - Capture web elements or entire layouts as clean vector layers and paste directly onto your Figma canvas. • Customizable Hub & Store - Pin your top favorite micro-extensions for instant one-click access. - Search and filter tools by category (Typography, Design, Developer, Accessibility, Utility). - Sort by number, stars, likes, or alphabetically. HOW TO USE 1. Click the Extension Hub icon in your Chrome toolbar. 2. Launch any interactive micro-extension (Font Finder, Color Picker, CSS Inspector) by clicking its card or using its shortcut. 3.

Pin or reorder your favorite tools to customize your launcher. PRIVACY & PERMISSIONS • 100% Client-Side: All tools run completely offline inside your browser.
