I may very well be missing something in the methodology, but in trying to use the new point curve tone control, I'm able to place new points, just like PS, but am only able to edit them by sliding my cursor up and down in the image or on the histogram. When I select a point in PS, I have an option of nudging the point in any direction with my arrow keys, as long as it is selected. In LR 3b2, I find that fine tuning the curve is difficult with the point curve because the physical manipulation of the points in the histogram window is a little coarse, and when I go to slide an adjustment up or down within my image, it often places a new point right next to the old one. In trying to select the extra point that did not want, even when the point is selected and dark, the delete key deletes the entire image instead of the adjustment point. I can undo the action, but I'm puzzled by why they would only halfway implement Photoshop's operating procedures with this option they have now given us. Am I missing something? Often the parametric curves are better, but sometimes I feel the need for more specificity, and am quite comfortable with how Photoshop works in this regard. If you don't abuse it and make an overly lumpy curve, it is a nice option to have.
