Who here uses darktable? What tools do you use most, what's your process?
I Recently saw an image, Don't know whether it was on /g/ or /p/, of someone using Darktable and having one of these sliders that you can move across the picture to apply or undo the changes you want and quickly compare them across the image.
Does anyone know how to get that effect in darktable? Running on Ubuntu 16.04
