Two suggestion for CC3 - 
1. 'Skin mesh' which deforms/slides with the rotation of the eyes, creating more realistic eye animation,
2. Morphing textures, in particular for the face, so that wrinkles would appear (and could be controlled) as the mesh morphs change.

[oops - I've already suggested these features earlier and forgot lol - clearly something I think would be good.
Sorry for 'reposting' - can't delete once posted]
