We’ve had a client dealing with a really messy maps / search / post location problem for some time. When the new map field came out last week we decided to bite the bullet and overhaul their site to use the new Google Maps field, and we extended our WP Ultimate Search plugin to handle the map data. Check out an example here: FoodTrade or see a stripped down version on our demo site.
So thanks for the new field! And have a nice day 🙂
