Shoutbox

I use StuffPlug for various things, one is, so that I know when a contact has closed a window, ie. "Someone has left the conversation" message comes up in your conversation. Normally, before tabbed convos, it would just say this and would not alert you via the taskbar. In the tabbed conversations, the tabs flash when the message for "left the conversation" appears. Anyway to avoid this? apart from switching it off in StuffPlug.
