@amyworrall beaker curves, and their handles, are awful things to interact with. I quite like Hobby Splines. The control points are much simpler, and the generated segments are beziers, making rendering trivial. Keynote offers these (change a point type to “smooth”).
@seanreilly I think we discussed this as a concept at least a decade ago! I love that it’s happening, and that people who think more about security than we do are on it.
