"rotate" display?

i have the need to have a specific resolution in portrait mode. however it appears the virtual display driver does not support rotation. is this something that is on the list of features to add? it is a pain to slowly try to expand the display by dragging the window to the size i want - i can never get it right and end up with odd-numbered resolutions 613(w)x891(h) for instance when i want 640(w)x900(h)...

 

I too would like a way to change orientation of the VM from portrait to landscape. Even if it wasn't dynamic and something I had to manual change in the settings (vs a quick button for repeated changes). Right now portrait mode sticks in a fashion that is top=left, bottom=right on my screen and this is not helpful. I do not with to orient my entire display of my laptop for this one piece of software.
