This does not do what it says it does on 1.8.4. Nonfunctional, a waste of money. The developer is nonresponsive to giving assistance so I'm to conclude that it isn't "just a bug" or something but, rather, just complete incompatibility now, abandoned. Don't waste your money.
Really great plugin! Thanks! First I had some problems getting it to work with the google maps api. Deleted the api key and made a new one and it worked. Maybe I misconfigured it at first. So check your settings and everything should work fine. :)
