Since the naming scheme for kerning classes is so often the same, I am wondering if I can import mine from one of my previous fonts or from a text file?
There’s a mekkablue script that does this: something like “Steal kerning groups from font”.
Thanks, @SCarewe !
Or use “File > Import > Metric”, open a .glyphs file and check the “Import Kerning Classes”. Select all glyphs you like to import classes for.
