P: Amount Sliders on Most LR Classic Panels

We have amount sliders on masks, presets and various other individual features (eg. sharpening) but we don’t have them on the panels themselves.  Particularly the color/tone panels.  These would be very helpful in fine-tuning changes made without having to change individual settings within.  

How many times do we make our Tone Curve, Color Mixer, Color Grading, Calibration changes to get the perfect colors then walk away and come back the next day to see that we had over (or under) done the changes.  We then need to go into each panel and tweak the individual sliders to fix.  If we had amount sliders on each we could simply dial up or down the amount of the panel.  Exactly as we can do with the masks.  This would save a tremendous amount of time in my edit workflow.
