Thanks for the feedback. Double-storey ‘a’ does make things busy. I’ll see what I can do with optional single storey ‘a’ as a stylistic set. The problem with stylistic sets is no one uses them and they’re not well supported in programming tools. I’ve got automated font file generation script in Glyphs app that generates all variants as separate fonts, so users can download whatever they want. I’ll try to create a single storey ‘a’ as an option, definitely for italics which are still under development.
