I know that I would be able to make do without individual cropping, but I'm sure other people would be able to get use out of tabbing between images on the crop tool. I think the main thing about the design that would possibly trip me up is if I HAVE to adjust the sliders or cropping differently and don't have an "Apply to all" button. It'd be quite a pain to have to flip through each frame and try to make the settings match up.
