This looks like an incredibly impressive project. Kudos to the authors!
Since it's such a huge undertaking, I think it's worth listing somewhere why we need a new editor instead of "just" improving GIMP and/or Inkscape. Is there an architectural change the authors wanted to make? Just to write it in Rust so maintenance is easier or more fun? (Which would be completely valid.)
As someone who worked in graphics professionally in my eyes Inkscape is clunky and other than with blender, this unwieldiness is not very systematic — that means I don't have the feeling I can learn a few principles and apply them in every corner of the software (e.g. modifier keys).
Some things that should be straightforward are not, other things that you never need are strangely easy. Granted as a professional you care mostly about getting things done and have a different (higher) standard about small papercuts and rough edges, because it is software you use daily. As a graphic professional I cannot use software that regularily crashes when I change fonts.
But I can understand the urge to make something new, clean, well thought out and open source in that space — because it doesn't exist. Illustrator is one of the things keeping me from going full Linux (although I use inkscape when I am on Linux).
