I recently was approved for the upcoming Google Maps interface changes and I must say I like it a LOT more than the previous interface. Going back to the current interface that is the “official release” everyone uses at http://maps.google.com seems old and clunky now. This gives me some new UI design to aim for with the Store Locator Plus product line.
Here is the invite with the link to the preview site. You’ll need to sign up and get approval before you can use the new Google Maps site. It took 3-days to get my request approved. Your results may vary.
