I'm missing the ability to remove / delete a specific desktop. The only workaround I currently found is the one stated here: http://dexpot.de/forum/viewtopic.php?t=5737. This is not really a feasible solution.
I could imagine right-clicking on a desktop in the "Configure Desktops" screen and choosing "Delete".
Or use the already available Dexpot control "Remove desktop" to assign a key command that removes the currently active desktop.
Since I constantly add and remove desktops, this would be a very valuable feature.
