- Why does it expand the path itself but then adds some sort of second, live expansion outside the path, a la Illustrator?
- Why you cannot undo it anymore?
- Why does it apply effect to ALL glyphs?
- Why does it slow system to a crawl and eventually crash the app?
The gray extra outline is the ‘Show offset preview’ from the view menu.
Thanks. What is the intended functionality? Could you link to its changelog?
This “Preview Offset” reporter is used if you have a “Offset Paths” filter in your instances: https://glyphsapp.com/tutorials/monoline
