TODO:

• Functionality is as advertised. Though the app declares requesting ACCESS_FINE_LOCATION, this is not accessed automatically, nor when browsing the map – but only when told by the user to use the current location, which is very good. Unfortunately, it cannot be toggled off again without killing the app – which a future release will hopefully fix.
• Button Styling
• implement 'Strassenverkehr'
• make a usable ui
