There should be a user-definable maximum number of vacation days that can be used in any game/tournament/round. I played in one tournament where a player used OVER 100 vacation days. That's just stupid.

There should be some implementation of restarting timed-out games. This opens up a whole new can of worms in tournament situations, but there is surely no reason to forbid a timed-out game between friends from being restarted.

I should be able to save the default time for games that I want. I prefer Fiscjer's clock with 7/0/7, but I have to change it every single time I start a new game. This should probably be done on at least a family of games level. I.e. I should be able to set my pente games to default to 7/0/7 and my espionage games to 30/.5/30, etc.
