Not so long ago, Google felt it necessary to remove the useful Play Store feature which allowed users to see which apps you'd paid for in the past. What we're left with, is a general summary of every app you've ever downloaded (even those deleted from your device), and while this is not a problem for many, the old system certainly didn't need any alteration. Thankfully, the old system that allowed you to view only purchased apps has made a dramatic return, in the form of a third-party utility called My Purchases.
