When a UFO file is changed on disk, Glyphs asks me many times if I would like to reload it. Checking “Don’t ask again” does not stop it from asking again.
Changing a UFO font while it is open in Glyphs is currently a very unusable experience. Running, say, ufinormalizer, while the font is open in Glyphs will give me dialogs that have no end and I have to kill the application to stop it.
Doesn’t it ask to confirm change in each changed file?
