It would be nice if the eyes and mane length (and any other I may have missed) dropdown menus would be sorted alphabetically like the rest of the dropdown menus. It's just getting a bit confusing the more eye colors and mane types we get. Especially eyes is a nightmare to pick already.

And then I would suggest to split poses and mutations into two different sections and add the piebalds to the other mutation section.
As far as I understand, no other mutation can have piebald as well, so it's pointless to give them their own section. They're basicly just another mutation.
