I've worked out how to drag items around in real time, but i haven't figured out how to use the 3D item viewer in the menus, does anyone know how to do this?
If you're asking what I think you're asking, just start dragging the item around and it'll rotate. The center of rotation is pinned. Also the mouse wheel will zoom in on the item, sort of.

The way this is going, that may be what all of us have to do to play the game considering the current keyboard controls are so illogical (and custom key mapping is so bugged).
