That works for importing groups, but not for the kerning table. It also doesn’t update groups who have the same name in the source font and target font.
I’ve been reading a bit more about ufo’s – if there are files called kerning.plist and groups.plist containing the ufo’s kerning and group info, can I use those to pass this information around between different ufo? If yes, how I can extract those plist files from my ufo?
