could the “incompatible outlines” error be more like the “these glyphs are not compatible” error, and group them all into one message/tab that opens? it’s currently difficult to deal with them individually when there are many of them
(I am getting this error from the variable rounding filter, but it’s currently expected that some will fail; others maybe not, though - need to investigate)
also for what it’s worth I think it’s complaining about inside overlaps, when it says “outside” (if I understand “outside” correctly), but glyphs like Oslash should definitely be failing. that may be a separate bug
