Perspective correction is irrelevant to me in this case, as is automatic rotation. It's the UI mechanics of cropping that are a problem for me. > Am 18.02.19 um 01:08 schrieb Robert Krawitz: >> I find the crop tool to be unwieldly for my common use case, namely >> processing a large number of photographs from shooting sports. >> >> I shoot a lot of basketball and (American) football games for my alma >> mater.
