Custom headers to put games under on the main menu
I know people have asked for a way to separate games they're in from games they're just watching before, and it's been pointed out that that would require the system to go in and check every game every time your list comes up...
"Doing it yourself," I'm not sure has come up before, though!
If this is reasonable, I think it could be awesome. I'd probably sort mine by speed. It would probably have to be something that you do in User Preferences, which might be a little bit inconvenient, but at least to me, seems better than trying to wedge a dropdown menu or something onto the main screen.
