Add a scrollable, zoomable, clickable World Map to the Login Screen so that users can login to regions much more quickly, easily and directly, rather than by manually typing in region names and coordinates, such as "Natoma/128/128/21", or "Da Boom/1/1/60".
The usual Home Location, Last Login and manually typed login point options should remain as they do now. But including the new option of "Use World Map" would make the alternative World Map login method happen too.
When a region is manually typed in, perhaps this proposed World Map should then automatically centre the World Map's view of this this region (and coordinates) too.
A World Map on the Login Screen could also show which regions are currently online or offline, as offline regions or ones restarting usually look "browned out", while the online ones appear normal.
A World Map would also be the new users first look at Second Life's world and would show these new users that the world they're about to login to for the first time extends vastly further than a Welcome Hub or InfoHub region.
I've imagined (below) a mockup of a Login World Map, using the default LL Second Life viewer login screen.
