Cosmic Panda Theme You guys should add a Cosmic Panda Theme, because I think it will fit better with the person who uses Cosmic Panda on their profile, and also uses Penguin Player.

Various things: 1: Try to be original and not only being old 2008 YouTube. You can get on legal trouble. Take a look at, for example, Vlare. It was a pretty cool design. I do not say that this design is bad, I say that you should stop trying to make it exactly like old YouTube. You can change it gradually.
1.1: I'd like to see annotations, but try to be original. Remove the "Channel 1.0", "Channel 2.0" and "Cosmic Panda" names and make the layouts more original and different from the original layouts.
2: I'd like to have the option for having a background music on my channel, so when an user enters to the channel, the music starts playing. If the user doesn't like it, it can have the possibility to disable the channel music. It can help on the customization of the website and make it even better than now.
3: When you change Vidlii to not be like YouTube, I would recommend you to make an app. It can really, really help.
4: Is silly to make the high quality only available for partners.
Thank'ya.
