I agree that the winning screen could use a slight rework at least. The crew roster with the score comes up so quickly after the match allowing usually just one or two ships from the winning team to be shown. I always thought pimping out your in-game character and showing it off is part of the game
A button to hide the GUI would be great (or simply moving the whole thing few hundred pixels down so it covers the legs and not the faces of the crew?)
The checkbox for rematch is unnecessarily big... Maybe emphasize there more the fact that the ships will be scrambled? I feel like the rematch vote passes like 10% of the time.
More stats shown after the match such as kills (for enginneer) is not a bad idea, considering the fact that ships usually run with a gungineer focusing more on shooting than repairs. The stats are recorded and counted in the profile so I don't see a problem showing the progress after a match.
