the new treeview is a very nice feature.
one thing disturbes me though.
if you create a custom window which jumps with you to the active connection ( -i ) the treeview item collapses on itself. it would be great if it would remember it's state. because now I have to open it each time I switch to a different connection.
please make it remember it's state!
and maybe modify the -z switch to also work for the treeview, putting the window in a special 'custom window only' section. because -z only works for the switchbar.
