Actually the subway stops ARE marked on the map, but indirectly. If you look at the top left of the map overlay you will see two icons. One switches the overly to the subway map. The locations of the stops are located and named there of course. Still, it would be nice to be able to set you destination to one of the subway stops
figure out what region you're in, check the subway map for the nearest region & figure out what street it's on, then create a destination to that street.
you can switch between the map & subway map on the main map screen.
I do that, but it involves a lot of map flipping. I'd just like to click on the street name on the subway map to set the destination. I know it's a bit lazy, but so is our ability to set a destination in the first place.
I also would find it helpful to see which locations have a subway station without needing to switch to the subway map. Sometimes I'm simply looking for the nearest station and knowing the route of the subway line/s is less important that seeing where they are in relation to where I am now. It's a pain having to switch between the two maps, memorising the names on the subway map in order to search for them on the normal map.
