can you add a quick switch, where we can quick change the view of an color photo to the black and white view of this photo. I would be handy to have a fast way to see if a photo looks better in colour or B&W.
PS. I love DxO Photo Lab, it is a really easy and modern Photo Editing Software with a good level raw converter. I have more fun to work with it, as earlier with LR6. I am really interested how you will further develop this app and what new features you will implement.
