It would be nice to be able to automatically order the channels by newest upload instead of a fixed order.
Where do you want it? On the video overview (usually displayed on the front page), in the channel list (usually ends up in the sidebar), or on both?
On the video overview (frontpage).
Would be nice if one could choose on both the video overview and in the channel list in the right menu, though.
It's actually pretty easy to implement; but I'm unsure if it's a good pattern -- if it's actually something which will be used in practise? The problem is that the channels will shuffle around on the list, making it harder to locate a specific channel for returning users (Why isn't the channel where it usually is?)
If you want to down-play the existence of channels, you can eliminate the grouping fully -- and simply replace the Overview (grouped) block with a Newest Videos block. You design can be reused, making this a easy switch.
This is how we built the front-page for http://futuretvlab.dk/.
I agree. My issue is that I have no left menu where I can add the channel overview. But I guess I just have to add that :)
