This is a really remarkable tool. One minor nitpick/feature request. It works great on Bezier curves, as you demo'ed in the excellent video. Unfortunately, it doesn't work very well with freehand curves. I'd like something like an O(4) Bezier curve, which the Bezier tool doesn't support. The plugin doesn't work on a group of O(2) Bezier curves, and if I draw the curve freehand, what comes out of shape bender looks pretty busted.
Thanks again for doing this kind of stuff.
