I think it would be very helpfull if we could have scripts create windows for the user, sort of like the camera control window or map window. Here's a good example of how a window will help:
LindenBall
Have a window that has a map of the field, showing blue dots for blue team players and green dots for green team players. Under the map it lists the scores for both teams and under that it will list who has the ball (and the font could be the team color). Perhaps even have a script that forces people to choose a team when entering the playing field through an option window that pops up.
