The Play Store's web market has come quite a long way since it was first announced back in February of 2011. Still, that doesn't mean it's perfect - among others, there are quite a few filter options still on the request list. For example, many users want to separate their free and paid apps in the My Apps interface. Thanks to a Greasemonkey script Artem just stumbled across, now you can.
That's not all this ingenious script does, either: it also lets you see all of your apps on one page by adding a resizable handle to the bottom right corner of each box.
