some way of swapping skins in game(more)

a while ago i posted about adding a radio like feature i don't know if the post got deleted or no but i believe i might of been the reason for the more options in music and sounds. that aside i have another really good thing you could add to your game ability to swap skins and cape in game a bit like you can do on bedrock but for java like you might see in mods like essential mod or other ones no paid cosmetics thanks 

and please add in the rotation of the music more of c418's tracks
