Type designers have known for a long time that Adobe Illustrator’s tools for manipulating beziers aren’t very good. Fontographer, Fontlab, Glyphs, and Robofont have all done much better. Making matters worse, most other vector editors are based on Illustrator, so there’s no good alternative that isn’t a font editor.
Lately I’ve been seeing lots of designers complaining about how bad the Illustrator tools are. Have we reached critical mass that we could get dozens of signatures on an open letter telling Adobe that their vector editing tool’s primary feature—editing bezier curves—needs to be redesigned?
