The 3p beta is amazing but ever since I started using it when it came out, the one thing that felt weird was the way it was positioned behind your avatar. By default when you enter 3p, it starts to zoom out above your avatar's head. I feel like this space in between feels a bit high for me personally but it's probably a good default.
Hence why I'm making this request to where the user can adjust this height in vrc settings :D
