It would be great if grips were added for rotating an object in the X and Y planes, not just only the Z plane.
You could turn these grips on and off by right-clicking a 3D model in the workspace, just like you do for showing roadside grading or design speed etc.
Currently, you can only change the rotation from inside the properties panel with auto update turned on which can be trial and error at times because you'll rotate it too far, and to get it exactly where you want you have to keep entering in rotation values which is alot slower than just having a grip for it.
Also, it would be great if the properties pane automatically checked auto update.
