Tom, I have looked into the rotation plugin and both documented ways need some kind of hardware to get it working.
CTRL-TAB function is what I need, just works fine mapped to a cab button. Ideally it would be possible to switch the different options (90 degrees, 180, 270, split screen) in both directions (maybe Left-CTRL and Right-CTRL) so one dont has to go through all of them eg. when going back from 180 to 90.
