If you're talking about a treeview switchbar implemented, this has been suggested many times. What you could do (before or if it is added) to free some room up on your switchbar is if you're on 3 servers, with 5 channels,sends/gets,@winows on each server hold down the Alt key and single click the Status Window. It then hides all the windows associated with that connection, holding down Alt and single clicking again "ungroups" them so they're all visible.
