Please give an option to automatically "grey-man" avatars above a certain performance threshold as an option.
For example, I would love to be able to disable all avatars (except friends, IF I choose.) for example above "good" or "medium" rating. This could be something we can toggle. I feel it would be extremely helpful to not only encourage users to have more optimized avatars handy for large gatherings but to improve performance on the whole for everyone.
