Love this extension, but also want to note that themes are a little broken at the moment.

Great extension.

Recently I experience strange behavior of the YouTube logo on the top left when using any colored theme. The color of only the first letter will change. For example, if my theme is mainly blue, only the capital Y is blue, the rest of the word ("outube") is white. I disabled other extensions, but I believe it's related to this one.

Nice functionality

cool

Very useful, and works so seamlessly that you forget it's there.

Youtube killed your extension man. Their awful interface is even worse now after getting used to your improvements.

Icons are easy to understand what they represent thus you know what changes you are able to make. This really has made my YouTube viewing much more enjoyable.
