I would LOVE some more options, especially for preset making! I always get annoyed I can't really see the stomach, paws, or mouth straight from the character creator screen, since I need to make sure everything lines up alright when I'm trying to test presets. I usually keep certain expressions hotkeyed so I can test them quickly in the little preset testing void but I often switch back and forth so often, it'd be much nicer if it were streamlined.
Even aside from practical reasons, it'd be fun to just mess around with poses and expressions for characters, too! I'm kind of glad the characters don't have much of an idle animation, since excessive body and head turning can be difficult when trying to create characters in other games, but I'd like being able to choose from animations myself.
