If it's not a huge amount of work, I think this would be very useful for non-3d modellers among your customers. Using simplified 3D modelling tools withing Unity, I spend a lot of time cutting out under layers of cloth meshes to prevent poke through when models are animated in games. Sometimes, though, there's a mesh inside another mesh that I can't get at and this often causes lower layers to poke through, making the clothing unusable. I've had this happen for clothes bought in the content store and elsewhere.

It seems like the element tool is much better at separating the various parts of a mesh since the update to 3.4, and it would be really handy to be able to delete problematic or unwanted elements.

P.S. Really liking 3.4 -keep up the good work!
