The chat module needs some serious reworking.
1. Too large and in the way. The module basically sits in the middle of your screen and can be very distracting while you are trying to play.
2. Have a history on the chat. Let people scroll up and be able to see what has been said.
3. Color code names as to it being a team mate or someone from the other team. I am always left wondering if that is a person my team or the other team.
I would suggest taking away the translucent background that is put behind the chat when someone says something. If it was just text, the module would not be as distracting. It would be awesome if you allowed people to resize the window and give it a minimum and maximum size.
I know the game is still in development so I am just dropping some suggestions that could help
