Future Character Creation Idea, Animation Swapping

[Evergrey]

I feel like if this were added, they'd probably limit it to switching between the masculine and feminine animations of whatever race you're playing.

Most likely.
But there are those races where the body skeleton/structure is different between the male and female counterparts that SE probably wouldn't even add that minimalistic option due to how it most likely would stretch/compress the mesh of a character.
And seeing how one of SE's reasons why not to add body sliders is because it would mess up the textures of stuff, implementing anything that could cause issues to textures is most likely an instant "No".
