One feature I found useful in Forger is an option to differentiate between finger guestures and pen sculpting With this turned on the pen is used for sculpting only and finger guestures are used for zooming, panning, etc only. This way you can let your sculpture fill the whole screen and still be able to move it around with your finger without the finger movement being treated as a sculpting action.
Does this option exist in Nomad (I have not found it), if not please add it!
Some users may find it best to use the finger for some scuplpting actions so it should be easy to switch on/off.
