I think it'd be great if the previewing option had the ability to auto center images on faces. Even if just one, or auto-zoom to fit each up to 100%. It would make culling images much easier if we could enable such a feature as we just use a keyboard going through the images.
I love that idea. We'd like to explore the use of AI in the future, but it isn't something we're exploring for Photo Mechanic 6.
