Histogram and Compare Image

When using the Compare feature to compare a corrected image with its uncorrected “as-shot” source image it would be helpful if the histogram tool reflected the respective images as you toggle between them. Is this possible?? I can acheive thsi by making a virtual copy and click between a corrected and uncorrected copy, but it would be much easier if the histogram worked when toggling images using the Compare function. I wonder whether the option to use the histogram to see/distinguish effects of local, global and combined adjustments (local+global) would be also be helpful. Anyone got any thoughts?

Good idea.
