Adds one-click sidebar links to Favorites, Saved, & Liked posts, plus a full-height Reels viewer with ultra-responsive snap-scrolling.
Of course. Here is a full breakdown of the script, a new one-line description, and a suggested new name.
What This Script Does
This is a comprehensive "Quality of Life" script for Instagram that focuses on two main areas: adding powerful, missing features to the main navigation sidebar, and completely overhauling the /reels/ viewer to be faster, larger, and more responsive.
Key Features
1. Custom Navigation Shortcuts (Sitewide)
The script permanently adds three highly-requested buttons to your main sidebar, giving you one-click access to pages that are normally buried in menus. These buttons are persistent and will automatically reappear even if Instagram's interface refreshes.
⭐ Favorites Button: Instantly view posts from your favorite accounts.
🔖 Saved (Bookmarks) Button: Jumps directly to all your saved/bookmarked posts.
❤️ Liked Button: Takes you to the "Your Activity" page showing every post you've ever liked.
2. Reels Viewer Overhaul (Reels Page Only)
This part of the script only activates on /reels/ pages and dramatically improves the viewing experience.
Full-Screen Reels: It removes black bars and forces the Reels video player to use the full height of your screen for a more immersive view.
Ultra-Fast Snap Scroll: The script disables Instagram's clunky, default scroll-snapping and replaces it with its own hyper-responsive system. A single tick of your mouse wheel will instantly snap to the next or previous Reel, providing a much faster and more satisfying browsing experience.
3. Collapsible Sidebar (Reels Page Only)
To complement the full-screen Reels, a small ◀ button is added next to the main sidebar.
Clicking it smoothly slides the entire sidebar out of view, giving you a completely distraction-free, edge-to-edge view of the Reels.
Click the ▶ button to bring it back at any time.
