P: Develop Presets: Preview adjustments in the Basic Panel Sliders on Hover

When hovering over a develop preset, your image shows a preview of how the image will look with the preset applied. When hovering, LR Classic should also preview the adjustments that would be made in the Basic editing panel. For example, the Warm Contrast preset should preview how much the White Balance and Contrast sliders will move if the preset is applied. The affected sliders should be highlighted in a different color and there should be a positive or negative number above the slider point to indicate how many units up or down that adjustment will move. 

This will help show how presets affect the image and will help you get the style you want if you like some of the things the preset would do, but not all of them. In the example above, if I like the new white balance, but not the increased contrast, I could hover over the preset to see how much the white balance would change (and in what direction) so I could make only that change manually. Conversely, I could see how much the contrast changes, apply the preset, and then revert the contrast the amount that was shown while hovering on the preview.
