the keyboard shortcut to switch to 3D mode for iGuidance is the number 3. You can easily make a button in most front ends, that will allow you to use SENDKEY to do it for you. This way you can have a button on your skin that you can tap to go to 3D, and tap again to go back to 2D view.
As for the coordinates... Yes you can re-add them back in by reshacking iGUidance. do a search for reshack iguidance coordinates, and you should find the thread with the instructions. The only problem is you will need a keyboard to enter the coordinates, as no one has figured out how to add the number pad back into iGuidance to do it via the touch screen.
