I tested different mapping modules, and loved IP Geolocation Views & Maps, but I can use another one if I manage to do everything I need :-).
I'm making a website for a movie production association.
I need to show different projections of the movie, so I made nodes for projection rooms, and node for projections (maybe they'll become entities, but that's not the point here).
I made a map with my projections, grouped by projection rooms, and the list aside. I also partly managed to detect user location, and center the map on it, with a default radius.
