The overlay that shows up when you rotate a crop is WAY too granular, like fine graph paper. If I'm checking a line from left to right across a 50-megapixel image, it is way too much trouble to follow a wafer-thin grid line 18 inches across a screen. You can't keep track of one line in such a fine pattern through all of the varying areas of an image. Allow for adjustable line spacing. I'd much rather grab a crop with just a rule-of-thirds grid and line up one of the lines in THAT, and THEN center the crop as desired, but you can't even do that, because the minute you click to rotate, of course, that fine-toothed grid comes back . . .
