Shoutbox

Personally I prefer it that way as you have many other options to be able to close all your chats individually, but no other to close them all at once.  You can middle click on the tab, press Ctrl+F4 or Alt+F4 to close them individually.  Maybe it has something to do with the new way Patchou does the tabs, but realistically I think that Alt+F4 should close them all at once like other programs that use tabs....
