Like I said, I haven’t looked into it recently, but a while back (maybe a year ago?) I had read a post about new Blender features that people were excited about, and one of them was n-gons, which is a surprising feature to be getting in just the last few years.
And again, while I haven’t looked into the current state of Blender–considering how basic that is of a feature that affects everything about modeling–it makes me wonder what other features it still doesn’t have.
