I'm currently on three IRC servers. When going offline for the night, I have to disconnect them individually, selecting each server tab and then using either /quit or File -> Disconnect. I'd like an /aquit <quit message> input line command that disconnects from all servers, sending the same quit message to all. There is already precedent with /aaway <message> and /aback (which I find super handy).
There should be an UI action that one can assign to a keyboard shortcut.
