So good that I actually wrote something here.

This extension is amazing and lets you customize how YouTube works and looks. Anyone that uses YouTube on a regular basis really needs this extension, because it will make things so much easier for you. Thanks a lot to the folks who developed this extension and to those who update it.

Works about 10% of the time. Very rarely shows any of the controls it's supposed to

super

I love being able to increase the playback speed. I was looking for a way to donate to the developer/creator. Don't see that so at least wanted to at least say thanks.

Very good extension, especially like the volume booster since everything seems to be quiet at 100% volume on my computer but half the time it doesn't even appear.

TOP NIVEAU !

I'd love some minor tweaks, like being able to change a bit more of the contraste, even some sharpening or smart blur, stuff like that.
