Its refreshing to see new ideas being implemented well. What makes this particularly interesting is the panning desktop metaphor (which seems to be getting more and more popular) and is quite appropriate for multi-touch screens (think ipad). It would be most interesting to see this idea extended in this manner, and possibly alter it so coding can be done differently. One possible way might be to have a collection of functions available, then link them together to create new functions. In most cases, this could be done using relatively few commands, so could be done on a touch-only screen.
