Similar to how Photoshop has facial recognition, a lot of the time in my job I have to place many headshots in a grid of frames, etc. and they're not all the same resolution, crop or size. It would be awesome to have a feature that lets you select all of the frames with face photos, then click one of the frames like setting the "key object" and then InDesign will size the headshot images within the rest of the frames to match the cropping of the "key object" so everything looks consistent.
