Yes, that is a pretty powerful part of MoI ( scripting + gui ). The combination really extends the possibilities of plain scripting, and it's a not readily apparent feature. It should be a strong selling point for MoI --
One thing that might be a good idea for sometime in the future, would be to put together a listing of all the methods and properties available for the gui and factories, maybe sometime after V1 or 2 is out? Anyway, there's alot that can be done with this, hidden beneath the surface!
