I love this extension. I use 2009 youtube, like 24/7 now. I just have some issues with the 2009 layout.
1. FIXED
2. Id like to at least play around with the star ratings, I know theyre not available anymore but it would be really cool if 5 stars was programmed to equal a like for YouTube and 1 star a dislike for YouTube. IK this is probably not possible but itd be really cool.
3. The autoplay button glitches the playbar layout. It just doesnt belong in 2009 YouTube, so itd be nice if it was removable

Overall, thats it. I love this extension very much!
