Good feature rich, but not in the settings department :( enough features to make this script crucial but also plenty of features that can be done without, which are in fact making the script bloated ...

Good When using the Tabview feature, the Info, Videos, and Transcript tabs overlap on top of the video player, which feels awkward. Please let me know if there is a way to modify this userscript or any ...

Good Would it be possible to make a separate version without the AI options? The script works perfectly but I'm not really interested in ever setting up AI on it. Thank you either way!

Good Works great! Question though, is there an option to auto-expand the video's description? If not, would it be possible to request the option, as including it would make this script perfect! Thanks ...

For example, the real-time live chat window is currently overlapping the original tab (which remains in the background), causing the chat to cover it entirely. To resolve this, I recommend adding b...

Is it possible to make this compatible with Violentmonkey? It's currently the best open source userscript addon for firefox.
