Welcome to Camera Bits Forums
In my workflow I edit images with colors and then tag them during a second "pass". I always use F3 to show "tagged" images because it's just so quick. Could it be possible to add let's say a "F6" function to show “Color Class None” images? This way I could work easily with keystrokes and shortcuts instead of always searching for the trackpad on the laptop just to click the bottom right section. I tried using "Edit/Select color class menu shortcut" but it will select the images, not show just the ones with a color class.
