I would like to see a way to blend objects together. Illustrator has this feature and it's pretty useful (the blend tool). Sorry for the unfair comparison, I really like what you guys are doing, I'm just trying to help you make a better product. You may have to do some interesting math, I think Illustrator takes the object with the maximum number of points and then maps the same number of points on the outline of the less complex object. Then you can calculate your angles, curves and coordinates.
