Help – iMolecular Builder Review

I don't understand how to download the molecules off the Internet, it is too difficult.please add instructions,also,it would be nice if we could create our own crystals instead of the same one;however,other then this it is a very good app and it helps a lot. This app needs a few updates and it's up to 5 stars.
