The R, G and B values under the cursor position are displayed in the Histogram palette. I would like to see the luminosity value as well. Programs such as Photoshop and Capture One display the luminosity along with the RGB values.
Admittedly, there are multiple ways to convert the three color channels to a single luminosity value. My preference would be for the same conversion as when desaturating the Master channel in the HSL control.
I realize that for such a tiny feature change, people are unlikely to want to spend a vote on it. Hopefully, the developers will slap themselves on the forehead and say “Oh, yeah, we should have included that!” and just slip it in somewhere along the line.
