So, on our channels, all the tabs at the top are directly related to the specific channel one is viewing... except for the 'Playlists' tab, which displays playlists from the whole of the sift. Instead, why don't we have that tab display only playlists related to the specific channel, kind of how we had the 'related videos' function on the old collectives... that way we can use playlists to sort the videos within the channels... for instance, like I am sort of trying to do with my channel:

War on Terror
-Raw Footage from the Front
-Interviews
-Documentaries
-Human Rights Issues
-Satire & Comedy

etc, etc.

Or, conversely, maybe we can figure out some sort of better interface to achieve such structuring.
