auto stack for similar images

When photographing birds (or wildlife in general) you end up with a lot of images of almost the same scene. Would be very helpful to let Bridge auto stack the similar images so we only have to choose the best of each stack for processing (or can be also more than 1). Rating we can do ourselves/manually. For this purpose, a stack should also be able to opened in a separate window (full screen), so you can make a good decision of which image to keep/edit.
