You can adjust the level of detail of the map display on the map using the mouse wheel or the overlaid +/- symbols.
When entering the starting address, vague information, such as Domplatz, Erfurt, may be sufficient to plan a route. The route remains zoomable, for example to view route sections in more detail!
If you would like to include one or more stopovers that are not currently on the planned route, simply drag the nearest route point on the map to your stopover.
The textual directions adapt simultaneously.
