When you get disconnected or enter the wrong login information, you're taken to a screen with a single modal window explaining what happened.
It takes way too long to leave the screen.
If you get kicked offline during an STF or other vital situation, the last thing you want to do is look at a useless screen for the many seconds it stays up. This is even worse if, like me, you have a complex password that you typo.
If you leave a Cube wondering around or are responsible for stopping probes in KASE, these are very long, very painful seconds just stopping you from getting back into the game quickly.
a) Cut the page change time by about half, or
b) Allow key presses to prompt an immediate screen change
P.S. I know this sounds like nitpicking but if you're having a bad connection and don't want to let your team down, this is a seriously annoying thing.
