There is one feature I'd immediately go VRC+ for: Separate Status tags for friends lists.
Let's say I am in a private game group. I'd want one small fraction of my friends list (friends 3) set to orange, "In Private Game Group, Ask if you want to be my +1" One to orange, "In Private game group, might take time to reply" Everyone else to red, "In private game group"......
Or if I am semi-afk watching youtube videos or something while doing a game in vrc... Green to one friends list "Semi-Afk, but around, might take a sec to wake" Orange to most "Semi-afk watching YT and housework"......
Or I might just not want to deal with certain people that day, but not remove them as a friend, and be set up orange or red to that list while being green or orange with everyone else.....
There are tons of occasions where I really want to be different status or level to different people and that feature would be one that I would pay for.
