I'm playing around with one of Blake's codepens from some time ago. I love the simplicity of the way it works without all the hassle of handles, etc. What I'd love to be able to do, is start with a simple line like that (with 3, maybe 4 points) and add the ability to click to remove, or click the line to add another point.
Had anyone done something like this? Something that would merge the 2 in a very simple way?
