Allow arbitrary locations / coordinates
It's only possible to choose certain locations on the map which do have a adress. It's neither possible to enter coordinates nor so select an arbitrary location somewhere in a green field.
Sometimes I schedule meetings of our group that take place at certain spot along the shore of a lake or on a nice spot in the woods or on a mountain. If would be nice if Mobilizon could show that location on a map and not just a close address.
How it could work
A user would be able to choose an arbitrary location on the map or directly paste coordinates of the form given by OpenStreetmap (47.0464, 8.4696) or similar. The location would then be shown as coordinates which could also be opened via a link in a mobile map app on a phone to navigate to the meeting point.
