Edit - Okay, I just realized it is possible to disable 'Message tab switch', great feature. But I would still like to see a chat box sizing option.
Having the ability to increase the size of the chat box ingame would be awesome.
I understand why this is the default setting, but now yall have given us the capability of playing in an enlarged windowed and fullscreen. Seeing the chat fly by in less than two seconds is quite annoying, especially when you're batch happy.
