The useful Refine Edge dialog consolidates all of Photoshop's mask-tweaking tools into a single spot, integrating them with several different types of previews. Unfortunately, the selection tools could still use some refinement; fixing selections like this one, which I deal with routinely--blown-out highlights against a white background--still require too much detail work. Since the Refine Edge preview is a great help at spotting selection errors, it would also be great if this dialog worked in Path editing mode, so that you don't have to jump back and forth among paths and selections when you discover you've missed something, as I did here.
