This script (based on YouTube Patch Collection) allows you to configure YouTube features & additional ones that are on a rollout, such as the new modern tabs, rounded player, you tab & more using yt.config flags!
This is basically same as YouTube Patch Collection by aubymori, but more flags you can enable/disable! By default, all are set to true, but you can set it to false if you don't like them.
Original script here:
https://github.com/aubymori/YouTubePatchCollection
WARNING: Not updated anymore.
This is why I created this version!
This will enable:
1. Rounded player
2. Modern tabs (title case, slightly smaller)
3. The You tab
