This addon gives me the ability to tweak youtube in so many ways and gives me options I didn't even know I needed until I discovered that I can actually have a choice about so many things! Fancy that! F.ex, I absolutely despise youtube's "autoplay feature" and now I am finally free of the damn thing! Blessed be!

If I could wish for a few more features, it would the option to hide / disable the damn chat box and chat replay garbage youtube forces on me, too.

Also, when I use "Use the whole viewport for the enlarged video player", I often manage to just nick the windows taskbar so the stupid preview / list view / tooltip crap pops up right in front of the control bar! I'd really be grateful for the ability to move the sliding control bar to the top of the screen instead of at the bottom to avoid that.

But all in all, as is, once you've tried this addon, you won't ever go back to the default, bare bones, featureless, choiceless old youtube you knew and hated before. Get it, while stocks last! LOL

Thanks so much Maxime for an indispensable addon. I don't know what I would do without it. 5+ stars!

Addendum 4 months later: The new UI is phenomenal! Brilliant! I love the way the Enhancer controls are now a part of the player's control bar and as the cherry on top, now I can finally choose to be rid of that damned intrusive chat box! Today is a great day! :D In appreciation; twenty bucks is headed your way. THANK YOU! 5+++ stars!
