This is such a great thread already! I personally would love to see more sliders and options for body diversity. Being able to change your pronouns or having them separate from character model would make me very happy, as well. More face paint and the ability to apply more than one, more hairstyles of varying lengths and hair textures, more selections added to the pool of facial features are all things I'd love. There is so much more that I could list but it will have to suffice for me to say that I agree with pretty much everything else listed by the people before me. There are things I never even would have thought of!

(Personally my "pipe dream" request is optional tails for Viera. I just think some fluffly little tails would be so nice, you know?)

Being able to assign hair to glamour plates would be really cool, too!

I love this game a lot and I love it's visual style. I hope someday soon they can improve upon their CC and more people can feel seen and represented by what they can create in game.
