It's limitless if you know JavaScript

I like this add-on. Only complaint atm is that it needs audio controls to fix audio sync issues when audio doesn't quite match video. There needs to be audio timing adjustments.

I don't watch Youtube without this extension

It's a good idea but I don't really want to read all this features. Therefore I recommande you to make it more designed and intuitive (you interface). Sorry & Thanks you

:-)

Makes Youtube so much easier to deal with. They're right, you won't want to use Youtube without the Enhancer. I've since bought Youtube membership, because it showed me how nice a controllable Youtube could be.
