Yeah, I have been wondering the same, the software should be smart enough to "know" what color range the user is picking. If I may add one more bit here is that the picker should work with a modifier key, for example Alt will enable the picker so the user relieve from extra redundant clicks. Just remember one thing... the less clicks the better. The current workflow is first creating the Adjustment layer, then selecting the color in the color bubble?, then enabling Picker and finally clicking on the image, there are total of 4 clicks. Now the new proposal is, first creating the Adjustment layer then holding Alt and click on the image, the total clicks have been reduced to two only, by doing this we reduce by 50% the amount of clicks and the program will become more ergonomic.
