It's easy to find a location within a Region by keying the name and X/Y/Z values into the World Map Display, but for Official Viewer users there's no way of establishing the position of the Region on the SL Grid.
Please could you arrange for the Grid Coordinates to be displayed next to the Region name in the bottom left corner of the World Map Display?
At the moment, you can find these in the Region-Estate/Region tab window if you're using the Firestorm viewer,
but NOT in the corresponding Official Viewer window
which seems an odd omission.
I have an Estate with just one Region, but people with more would surely find it helpful.
