By all means Lr is way better that Aperture, but Aperture had 2 nice features that I would love to see in future releases of Lr. The first one is the ability to see the focus points. Aperture had a feature that showed the focus points and also highlighted the one/ones that where in focus in the shot. The second one is that Aperture had this nice way to edit the pictures in full screen mode while the menus where floating. I know that Lr has its own full screen mode but the ability to have floating menus as in Ps and Aperture will be nice.
