This is a suggestion, in

PRO when a face was disabled the UV mapping for that face was also disabled, I was doing some work in

Studio and realised this was no longer the case and I was UV mapping faces which were disabled.
It's not the biggest thing in the world but it makes a little more sense to not be able to UV map diasabled faces and it would mean that anyone using

Studio wouldn't need to check which faces were disabled before UV mapping different elements so as to not waste time.
