Each of the RED features is again interactive.
Commercial/Public buildings are drawn in RED.
Clicking on any facility or home will lead to a file with information (or
perhaps none) regarding that facility. Eventually, all of the homes will
have addresses tagged to them that you can look for in the "find"
function.
The title of the map is interactive, and will bring you
to the district map (which shows where you are in the district).
The navigator allows you to move from map to map, at
the same level. Any red letter is linked to the adjacent map.
