I would like to see a magnifying loupe with enlargeable percentages that can be used on the contact sheets. The preview runs unbearably slow when enlarged because It is blowing up the whole file. I have a G5 which isn't the oldest computer but, the screen redraws are way too slow. If there was an option for an enlarging loupe, like in Apple's Aperture, I wouldn't even really need the preview screen any longer and could look at the contact sheets for composition and then use the loupe to check for focus. This is how it used to be done with slide film and think this would be a great addition to this program. Other photographers and I have discussed the other programs like Aperture and Lightroom and still feel that you can accomplish most of what you need with PM but, to speed up a work flow the loupe feature would vastly speed things up.
