The layout is just fine, gratz on that.
However, there are some major problems.
Why can't I remove unwatched, watched and unwanted videos?
Why is there a FB-button? First time, fine. But give me the option of removing it. The G+-button I want to keep, again, make it optionable.
Before, if there was 4 videos, it showed in a row from the same subscriber (or the other way around :) ), that's good. Now, if there are 2 or more, they are grouped, showing only one. If you see that, you can't remove it.
/home has been removed. index_ajax is a life-saver right now. When they remove that option to see the old layout, I think I'm done with Youtube.
