Hi,
I recently upgraded to Glyphs 3 from Glyphs 2 where I have used a custom “Groups.plist”. I created a new one according to the tutorial “Custom Sidebar Entries in Font View”. Then I wanted to generate a missing glyph by Ctrl+click–ing on the grey number (eg 0/10) but nothing happened. The pop-up list with the missing glyphs does not show up.
I thought I have an error in the “Groups.plist”, but I does not work even when I delete the whole folder from the Library or after multiple restarts. It is not working on any entry in the side bar now.
I am not sure if it even worked after the upgrade. I have not tried it.
