Yah, but making it bigger would help the most. It would allow you to quickly scan the players list. Also, is it possible to hide a player for a little bit of the game?
No, that's not possible at the moment. I will, at some point in time, add an advanced keyframing system which will allow one to do that. However I'll first have to fix most of the bugs and I'll write a post explaining my idea in detail before I start to implement it.
