The Camera Raw filter v9.6 clearly has a new GUI which follows the current look of Photoshop. Regarding the new look, I have one comment which concerns the sliders used in the GUI.
If I place the mouse pointer just one 1px below the indicator of a slider and move it to a side the indicator doesn’t move but the one below does. First, it looks weird. The cursor is like on the slider I want to move but in reality the slider below is active (see the images below). Second, it is easy to make a mistake when working with these sliders. You should keep in mind that people are not machines. They are not perfectly accurate in what they do. The current behavior of the sliders forces me to be more concentrated on the GUI than on the image I am editing, which is wrong.
Because the indicators used are very small, there should be invisible circle (or
square for simplicity) around them that would be sensitive to mouse
pointer position. When the mouse pointer is positioned inside the circle the
indicator should be active. The circle should have sufficient diameter.
