This is quite difficult to do. So lets wait if more people will find the feature useful.
To switch among sessions you may also use dropdown menu on toolbar, keyboard shorcuts Alt-1 to Alt-9 for the first 9 sessions and also Ctrl-Tab and Ctrl-Shift-Tab to cycle the sessions. _________________ Martin Prikryl
This sounds useful for those who regularly have multiple sessions open. But for those of us who don't, please make any UI optional; I don't really want valuable space in my window taken up by a pane I won't use.
