Often after creating a grade and would like to see how the whole grade would look if I lowered the overall intensity, without having to create a lut and do this in a 3rd party app. And then if I lower or increase the effect, the option to take a 'snap-shot' of the new dialed in amount, and build upon that to open up even more creative options. Sort of like how the AI has you pick from 4 styles and it gives you 3 more suggestions based off the one you chose from the previous batch of options. I hope that makes sense.
