Even though fur is more important to me, I probably use rounded edges more than anything else on that list. It's both a big time saver and an important part in surface realism. Wish this ranked higher in the poll.
I have a bit of a suggestions I suppose, maybe something done for the future after 2.0 or something.
Maybe make a simplified skin shader node? Like for instance, when you do texture painting for skin you create 3 layers, the epidermis, dermis and hypodermis. It would be interesting to have a node that can incorporate those layers and have settings for them. Like if you want more of a dry skin effect you boost the epidermis and maybe have a moister bar as well. I know you can do this using the mixed shader and stuff but it would be a nice simplification of it. I think Vray does something similar? (And maybe mental ray) I don't really use those programs so I'm not really sure.
Just a bit of a future suggestion I suppose since I don't think it's really a top priority sort of thing. Skin shaders can be made without it after all.
AS my requested features seemed to be different from other people's, I started a thread of my own, in the absence of any responses from OTOY in any other threads. Still waiting from a response from anyone in the development team.
