"Create a favorite" in context menu and favorite names
Not all streets/roads have their street numbers defined in OpenStreetMap so, on a back road in the middle of nowhere, you can't create a favorite at an exact location. I suggest to add a "Create favorite" in the context menu when we right-click on a specific point on the map, which would pick the exact GPS coordinate of the point where we right click and create a favorite based on these coordinates.
Also, favorites are automatically assigned their address as name and the only way to change the name of a favorite location is to change the name of the location in OpenStreetMap (there would be a ton of places in the world called "Home" or "Work"). Favorite should have a name that is independant of the address, that we could define either in the dialog box when we create a favorite or later when we right click on a favorite in the favorite list.
