I think it would be super cool if tail cosmetics were added. Personally, I have a cat skin and I would love to be able to complete that with a tail. There could be lots of different colors for lots of different animals, such as cats, dogs, rabbits, and horses. There could also be more fantasy like tails, such as dragons, kitsune, nekomatas, etc. (The picture is from the now discontinued mod called "Awesome Player Cosmetics" by GekidoLukas)
