In 2023, it’s apparently on by default, but the slider needs a manual adjustment. Why is that? If the software can detect pink areas and paint them pink, surely the software could also then detect what slider setting to automatically apply in order to remove them?
From a beginner’s point of view, this seems like unnecessary complexity which no other software has. What is the advantage of forcing the user to manually tweak this before getting started with that you really want to do?
