Req: Tabbed chat window?

[Serrin]

Would having separate windows that overlay each other exactly work? Each window could have a tab offset so that when you click on the new "tab" you are actually giving focus to a whole new window? It might give the effect of having one window with tabs, but could be up to 5 or so windows perfectly alligned over each other. Not sure if this is possible or desired, just trying to come up with an alternative that may seem to work.
