God I love content-aware fill. At Lifehacker I frequently want to illustrate a post with an image that’s not wide enough (like above). So I throw it into Photoshop, I expand the canvas size, I select the new blank parts on the sides, and I hit my cmd+option+F—my custom shortcut for Edit > Content-Aware Fill.
