An annoying thing with sp on pc (and probably osx as well) is that the button to allow the mouse to orbit the camera is the same as the button used to sellect and move a part, so if i want to orbit/rotate the camera i have to find a spot on my screen that doesnt have a part near it (good luck if you are building inside of part of your plane (ie bomb bay, inside of the cab of a truck) it is really quite frustrating, especially knowing it is a supper simple fix (add rotate camera, pan camera, select part, as option in the control menu)
