It would be fantastic if I could hold down a button while cropping my images. This way, regardless of the ratio I’ve chosen, the cropping becomes freeform, allowing for quicker customisations. Once I release the button (or button combination), any subsequent crop will retain the previously set ratio.
This is a workflow improvement, as most of my images are portrait 4:3 but I sometimes need to crop them slightly taller. This would save time by eliminating the need to swap between unrestrained cropping and the 4:3 constraint. Simply holding down a keyboard key could temporarily disable the 4:3 constraint.
