I think it is a very important thing you can import maps from others like ESRI or similar and with that import you can see the streets name or make routes the same way as the cities that MP have inside originally.

The only way to import data maps form ESRI is by the add-in Spatial Data Import, but this one only draws polygons and polylines ... you cannot see street names, you cannot find any street of the imported city, you can modify the vertex of the polygons deforming them ... IT'S NO SO GOOD.
