Any news?
Just stumbled across this thread as I also need a solution for merging layers on export. Is there any solution for this? Thanks!
Just tried fixing the plug-in above. I can get it to be called in Glyphs 3 on export but it seems what the plug-in can access is practically sanitized. The layer’s parent (the glyph) has all other layers removed, and all additional masters in the font are removed as well.
What can I do? I think this is a reasonable request.
