Impressive! I think a "Lathe" tool could be made from your "Draw" shape tool fairly easily.

Interesting problems you have... Balancing flexibility/power/precision and simplicity/low learning curve/finger input.

I'd be tempted to go more the flexibility route... but what is essential? for who? Where's the line drawn for "dead simple"?

Would precision for the "drafters" slow down/confuse the "doodlers"?... Could build flexibility underneath and carefully build an advanced UX that people can graduate to, but at what costs?... At what point is the focus lost?
