YouTube Alchemy — Tim Macy

This toolkit offers various features and customization options for YouTube, such as tab view, speed control, export transcripts, square design, auto-theater mode, sort notifications chronologically, and much more.

Videos on the Home page can be color-coded with borders to quickly identify their age and status, while the last uploaded video on the Subscription page can be highlighted and optionally auto-scrolled to it on subsequent visits.

Want to add a link to your favorite channel, video, or to a completely different website? No problem! Up to ten links can be added next to the YouTube logo.

Please use GitHub for issues and feature requests.
