I’m wondering if this feature (making it possible to load plugins via ~/Application Support/SketchUp/…) is still on your to do list?
I just checked in 2019 and it still doesn’t work. I’d love to know if it’s supposed to work and I’m just doing it wrong?
It’s pretty icky to have to copy a plug-in into the app bundle, and it looks like this was a thread from 5 years ago. Would be great to see it get bumped up in priority.
