For future CTA releases, I think it would be helpful if there was a way of generating a shadow beneath a character. Currently it can easily be done manually, but it is one step that might be able to be an automatic process, thereby speeding up project completion time.

And while on the topic of shadowing and lighting, it would also be nice if we could add illumination to the edge or outline of a character, as if a light were shining on them. I feel this, along with a shadow beneath a character, would give the illusion of characters having depth and being grounded in to a scene rather than being simply stuck over the top of a background.
