Currently (from my testing) I've noticed that the phone trackpad seems to be mapped exactly to the whiteboard. The only problem is, the whiteboard is landscape and my phone is portait. This causes the horizontal movements of the trackpad to be SO fast and difficult to control, and the vertical movements to be longer and more uncomfortable than they should be.
I think it would help to have the trackpad adjusted so that instead of movements being units of the full vibe screen size, they are instead units of equal distance vertically and horizontally
