The latest addition, which was pretty much just part of the category implimentation, is the ability to drop all your pins from a category.

No matter if it is a custom category or a default one, drop all the pins to pinpoint exactly the type of venues you are looking for in your surroundings. If at any time you wish to show all your bookmarks again, simply tap the ‘refresh pins’ icon and drop-away.

Yet another major improvement to the map app world.
