Happy to have made you discover something cool :-)

> 3D top-down view is the most comprehensible-looking map I've seen in a long time

The 3D top-down view with building heights is possible thanks to OSM providing this data, thanks to people improving the map with apps like Street Complete and Every Door. Make sure to check them out :-)

There's with this 3D view though: it sometimes hides streets. I usually end up disabling it at some point.
