I just watched the marketplace update and had a thought. To give users a bit more personality/customization, maybe have the ability to take one's gallery or sticker library and place it on their avatar.

I'm picturing the system would mirror your avatar in front of you like when posing for FBT, and the UI similar to sticker placement but it only affects your avatar. I'm thinking it would be a VRC+ feature as I think the stickers are.

Options to hide/show decals should also be added
