so you have long configuration names and want to see them all
ok, i'll think about resizeable control there (though there can be strings that dont fit any control..)
The left pane would be better suited as a small toolbar. One laid out almost the same as it is would be fine, but if it were turned into a horizontal toolbar all the same info could be provided, but there would be TONS of space for saved configurations
not quite understand what do you mean..
