COSMETIC NAMETAGS is a mod that adds a trinket slot for a nametag, which changes your username above your head and in chat.
VERSION: 1.20, 1.19.2
PLATFORM: Fabric
REQUIREMENTS: Trinkets 3 or above
I'm working on bringing it to other versions, but it's a lot of menial labor and I work at my job and on my other mod Beetlebox a lot, so let me know if there's a version you'd like me to prioritize.
Feel free to use in your modpacks or servers, as long as you're not repackaging the mod and offering it for download yourself.
