I know this has been suggested before, but I'd love to see a button which populates the make.php form with random characters and backgrounds. I don't think it would be hard to make, and it would spawn a lot of creative ideas.

I agree!

And maybe a WTF competition to join the BTC and FTC...

If this goes ahead though, I'd like to see people encouraged to hit the clone panel button on the first strip as often as possible- while a lot of vets can probably work with anything and make something clever, there are always a lot of people coming through whose strips are fragmented enough as it is.
