I am very disappointed with the application. There are big bugs regarding alternate glyphs. When I import new alternate glyphs, Fontself changes the order of the alternate glyphs! The new ones become alt1, alt2, alt3, etc., and the oldest ones are shifted after: alt10, alt11, alt12, etc.
Additionally, you can’t even manually rename alternate glyphs.
This is why it is impossible for me to design a font with this program. This is extremely disappointing.
EDIT: I currently have 2240 glyphs including 2022 alternate glyphs. So this shouldn’t be a problem, right?
