When cropping and straightening a photo, sometimes transparent space is left and cropping to eliminate is not desirable option. There are workarounds to fill the transparent pixels. I would like to suggest adding a Content Aware Fill Layer to the Context Tool Bar. This, if enabled, would fill in the transparent pixels from averaging nearby pixels or any method development team decides, to fill transparent pixels. My concern is for the tool, not the method. Those that don’t need it, don’t tick box to fill.
