Here is some ideas/questions:
*I can develope lots of different chape of trees and that is excellent. Mayby later you develope this feature to develope even more complicate tree models).
*some reason I can't develope different kind of forms of rocks, I mean program only creates same rock withouth any new chapes (mayby I need to read manual more)
*in store page pics I can see cactus, but I don't know how to generate it
*Feature to develope grass and flowers would be awesome too
