Video Enhancer makes highlights, black levels and colours so much richer, particularly when watching animation. Love it.

My 2 suggestions for improvement. Firstly it would be to use a "ON" icon and "OFF" icon representation for Video Enhancer on the toolbar when the Video Enhancer toggle is enabled vs disabled. That way you wouldn't have to open Video Enhancer to see if Video Enhancer is on or off at any given time, you could tell simply by looking at the icon itself on the actual toolbar.

The second thing would be to set a per website or per tab manual control for Video Enhancer. This sort of automation would offer a lot of flexibility.

The colors look so much more vibrant when watching anime. The UX is great too!
