I like this idea. I will often pick out the "one on one" games or the quicker to play games first. That way, I won't leave someone more or less waiting for me to finish waiting while I take 15 minutes on Waterloo. I also tend to play all of one map consecutively, which means I stay in the same strategy "tack" more or less.
Granted, I can always just go into My Games and pick the correct game, but this feature would be nice.
A problem I can forsee -- if you forget that you "skipped" a game, you might end up deadbeating. I would therefore suggest it go to the bottom of the
ACTIVE games -- maybe add one second or one minute to the last active game on the timer, for example. OR, have it reset automatically when you leave "my games"/ log out of CC.
