It would be nice to keep most avatars turned off but also have an option to manually toggle on avatars for specific individuals WITHOUT seeing their shaders, particles, animations, ect... (like custom safety settings)
The only option we have right now is the "show avatar" button and it overrides the safety settings which isn't ideal in public worlds because of crashers/performance loss.
This would also be a simple way to increase performance & minimize bandwidth for a lot of players! (if they choose to play like this)
