hi all. I wonder if this thing exists? ---a way to set my preferences for two settings, one for high quality all-stops-out, for viewing great distances at high quality; and the other settings for when I am in, say, a crowded club with 20 avatars, when I need a very low quality settings?! maybe have a keyboard hotkey to toggle between them. using the preference panel for *each* change might soon get tiring. thank you...freestone wilson
