When a burst of shots is taken, a little bit of camera move results in the subject being positioned in a different place across multiple frames. This happens a LOT in sports when the subject is moving and you're panning to follow...
WISH: When processing these bursts and cropping-in .. it would be SUPER USEFUL to (a) crop the first image in a series to the framing you like, and then (b) go back to Grid view, select multiple photos and choose "Crop Series"... which would use AI to position the crop rectangle so that each image in the series would keep the subject in the same spot in the frame.
Today you have to do this manually .. and it takes forever to position, resize the crop rectangle so each frame "matches". It's particularly hard because LR doesn't keep the frame size/position constant when you're flipping from one image to another and engaging the crop function. (eg. you can't "point to a spot on the screen" where you want the head to be.. the UX jumps it around.)
