Super Address field is created to have a single field for address. You can have Address 1, Address 2, City, State, Postal Code, Latitude, Longitude (and a button to fetch lat/long from given address). This field type supports GRID and Fluid too.
You can use this field to filter Low Search results with distance. Plot location button that fetch lat/long from address makes it complete solution for address saving.
