Very good- room for improvement

This has been a great tool for communicating with clients. I have a few suggestions for future upgrades:
My clients tend to find the user interface hard to use at first. It responds too rapidly to user input- you try to move a bit and find yourself on the other side of the building. There are "tricks" to solve this, but this only gives the impression that its more complicated than it is.
The same surface is rendered differently depending on what kind of element its applied to. I have a model with gypsum board on the walls and a barrel vaulted ceiling and the ceiling is darker than the walls (no, this is not the result of lighting!)
It would be great top have access to layers in the iPad app as we do in the desktop version.
Navigation in the desktop version is even harder than in the app. Rotating the model is especially difficult.
Id like a grayscale shading option in the app. Clients get bogged down by materials when they view a model. I dont want to create a model without surfaces just for BIMx, Id like to be able to turn them off and have simple grayscale shading instead.
