Withdraw from tournament @ end of round

It would be nice if you could select a tick box that withdrew you from a tournament and let the second place player progress. If i decide i don't want to continue with a tournament i have to resign all my games (which show up as losses in my stats) and basically ruins the tournament (especially if it's a final) for everyone else. Allowing players to withdraw before they progress makes sense i feel... 🙂

EDIT: Also this could be used to automatically remove players who are massively over a rating band. A 1500-1600 tournament shouldn't be won by a 2000 player...
