As a semi-retired user from way back, I find the lack of development of Hair means and methods a big turnoff.  The hair room has always been horrible, and going into 2016 (Presumably) without any changes...it just seems like the elephant in the room.

 I'd welcome even a separate program dedicated to hair creation that works in real time, much along the lines of Marvelous Designer and the way it handles cloth.

 Just...something.  I mean we're 15 years into the 21st century and it still feels like 1999 to some degree.
