There is already a request for user-based chatbox override and integration into the safety system, both I think are very useful, but I think another option would be useful (yes I know, more options wheee) is a toggle to make the chatbox visibility respect the earmuff distance (the red line specifically).

This would allow users to limit the visible chatboxes to only the users around them that they are talking to, and save them the trouble of hunting through crowds of people's selection capsules or though the social menu just to disable the voice (or in future override the chatbox) of a specific user who's doing the annoying chatbox spam stuff.

it's a logical progression of the chatbox being (currently) tied to mute as they both are "user speech" mechanisms, no?
