Lightroom Classic Color Grading tool needs additional saturation controls.
Perhaps it's because this grew out of the split-toning feature, but this new tool seems to miss the most important functionality of a "color wheels" grading feature, which is to independently control saturation of highlights, midtones, and shadows. The current tool always applies a tint to the various tonal regions, and only allows you to increase saturation of that tint. Fine for your favorite weird color effect, but the saturation sliders for each region should be independent of a tint, allowing the user to increase or decrease the saturation of native colors of the document separately in highlight, mids and shadows. Its a powerful feature that all video coloring programs have, and none of adobe's photography apps have. I was so surprised to see this functionality didn't exist in this new tool considering how it's been hyped.
