It is extremely difficult to correct a wide angle shot taken at an angle to straight geometric shapes, such as trees or buildings. Lens Corrections>Manual>Transform probably has all the tools, but in some photos it would take a computer to know which ones to apply and in what order. The Straighten Tool in the Crop panel is brilliant (and has been around in PS for years). Can we have something similar in Lens Corrections, where the user would draw a few straight lines in the image (essentially telling LR what's a building and what's a tree), and LR would attempt to apply the right Transforms to straighten the photo?
