This is great. I don't think I would go back to using YouTube's default layout if I could somehow see my subscriptions on the homepage.
It would be very nice, though, to be able to add videos from my subscriptions to my watch later list, and then watch that playlist while being able to reorder/remove videos.
What I'd really like is a quick way to dismiss some of the videos from my subscriptions that I don't want to watch. That way I can come back again later and see only the ones left. I realize this is really just a 'watch later' playlist, but I'd prefer to remove things (permanently) from my main subscription interface.
Great work so far though!
