In SL we can set to show the Avatar Names Temporarely.
This is quite useful when we've been in a very crowd room; after a while, all the Names and Group Tags only difficult our vision, and use up resources that we rather were used for something else.
But, I think it would be useful to add a keyboard combo option to show all the names again for a short period of time.
This comes in handy when we forget the names of the Avatars around us.
The "long run" alternative is available now: See their Profiles (sometimes is hard to click on them when they move fast or go behind other objects) or return to the Preferences window and set Show Names to "Always".
I appologize for my ignorance if this option already exists, or if it was asked before and it is coming in a new version. Thanks,
