Because YouTube shouldn't fix things that aren't broken

About

A.K.A. Why did I make this?

'Cause. In my eyes, the latest change to the YouTube theme is completely unnecessary and ruins what was a fine UI before. It's laggier and looks worse. Therefore, here's the solution. An extension that allows you to switch between them. If you appreciate what I'm doing, drop me a few bucks over on Patreon. Thanks.
