The first Chat Tab in every server is named after the server.

sometimes this will bring up a very large and odd tab.

maybe just name the first tab "Global Chat" or "Server Chat" or something like this?

Or give the user a option in the Virtual Server Edit, to rename this Chat Tab.

Another cool feature would be if it would be possible to "drag" the chat tab out of the client as a "extra" window. As multi Monitor user you can easly chat on the mainscreen with a chatwindow, while the main TS3 Window is all the way at the other side of the second or third monitor.
