Histogram view specifically for curve adjustments

Broad image contrast, or eyeballing an S-curve doesn't always work for me. If I have a high key image, it will largely just make my image brighter. If I have a low key image, it'll get darker. Adding contrast requires more of a custom approach for each specific scenario.

It would be nice to get a histogram in the curves adjustment window. Similar to my second screenshot within photoshop. We have histogram in the image editor, but that requires a separate area and some eyeballing.

Thanks for taking the time to read this!
