I think it would be awesome to have the ability to use bezier curves when editing head shapes in the front and side views. This ability would significantly improve the product and make it much more user friendly when having to position points and the curves that get squished too much and deform the mesh improperly. I find I can never actually follow the contours properly because of this limitation.

Not sure how easy or hard this would be to implement, but all I know is this is my biggest gripe about this software. Without the ability to rotate and scale my points as with a bezier curve that can be broken with different weights. Well, some of the faces I have worked on have not been what they could have been and I always find I have to edit the heads in another program to correct the bad mesh structures produced. This would probably help lip sync and expressions as well, as it would lead to better mesh distribution were needed. At least I would think this to be the case.
PLEASE ADD THIS FEATURE!
