Nice to hear that hehe :) You can also meanwhile make all the sheet cell formula enabled (an exemple is with the mRPG app)
You can go see the official website to see all the update and features. Take some of the basic from them :-) If you combine the character sheet from mRPG and your 3D map platform it would be AWESOME.
Ohh and the fact that the app is on all the device (ios, android, window etc.) is one of my favorite thing of the app. I can play while i'm working :O hehe
