Well, I suspect I won't be missing Photoshop Elements for long based on the rave reviews I've ready about PM, but I have been using Elements' Organizer for several years and have grown accustomed to its ability to "stack" (within a thumbnail) multiple versions of the same photo. That way, when I browse through my photos, I don't have to look at all 10 versions of a particular photo; I just see the photo I've designated to be on top of the stack. I am new to PM (just installed the demo) and can't seem to find a similar feature. Is it lacking? If so, is that because it has some other (better?) way to manage multiple versions of the same file? Do tell.
