1st:

Please add an option, which I can mark an specific avatar as "Friends only" or "VIPs only". Other players will not download the according VRCA-File and are not able to rip it's content. Other player will only see the fallback avatar.

2nd:

In the friends list, add an option to mark a specific friend as VIP. Let me also set an option, to allow VIP's to join me. Others will see "In private World" or "Offline" only.
