I'd like to see either the ability to add a pair of horns to any model (with several varieties of horn, on the front, side, bigger, smaller, different colours), maybe a halo as well, or a special hairstyle with the horns/halo option built-in and able to fade in and out (this version would require several different hairstyles, so you don't end up with every Demoness/Angel looking like they go to the same stylist).
The ability to change textures on skin and eyes is nice, but I really want to be able to make fantasy characters that aren't JUST "skin-deep."
As an example (the following images were made with Poser), I don't expect horns THIS impressive...
But even smaller horns would be nice.
