Dear John. Please arrange for Adobe to implement the following feature for me. I love the "Visualize Spots" checkbox in the LightRoom / Camera Raw "Healing Brush" as a way to locate dust spots that need to be cleaned away. The problem is, you need to be zoomed in at 100% to effectively deal with sensor dust, and sometimes it's not clear whether a particular mark on the screen is a fault or a feature. Then you need to click to normal view, and back to the edge-detection view. It's a problem having to move the cursor down to the checkbox, back to the spot to clean away, and back to the checkbox. A key-chord combination to enable and disable the edge-detected view would be a great benefit ... and there are so many to choose from! It could be Ctrl-H, since it's a Hide operation; or like overflow/underflow indication, it could simply use the control key. Only while healing, you understand. That's all right, no royalties are necessary. Tom 16 J...
