the mute feature of SecondLife should be revamped and be made more robust, with features to include just how "muted" you want the particular resident or object to be. ie.
allowing you to completely erase the person or object from your screen.
allowing you to replace their model with one of your own maybe like a red box saying something like "Muted" on the sides (on your screen of course)
im sorry but some people/objects are just repulsive and even having to see them or the objects in question degrade ones SecondLife experience.
