Glyphs 1.3.17 (429)
It seems that if you try to Undo after adding new Glyphs, you are left with a bunch of empty newGlyphs.
To reproduce:
- Add a new glyph
- Edit::Undo (or Command-Z)
See that empty newGlyphs are leftover in the Other section of the Font View.
Earlier, when I noticed and tried to delete them, Glyphs hung. But, I haven’t been able to reproduce that situation with barebones empty fonts, yet.
