Lift adjustments and or metadata. So that you don't have to select every image first to add the adjustments but also during your work. Lift for instance your exposure or ither changes and stamp them later on a shot. This becomes handy as first edit now i have to go back an forth everytime to the shot. When lifting you can just stamp the shot which you want to have the same settings or metadata or what ever. Great function that was in aperture that is really miss in Lightroom.
