Slideshow is a handy tool for sorting images while having the largest possible viewing size, relevant on a laptop or when running through images with a client/clients. Except for one thing. While tagging an image with += or T works, the tag status does not update while still in Slideshow. Hit escape to go back to Contact Sheet and the updated status is there. Live, immediate updating of Tag status in Slideshow would be super useful.
