Both Adobe Camera RAW and Lightroom conveniently display the levels for Red, Green, and Blue directly under the cursor or eyedropper. Although each has a different approach (ACR uses 0-255 levels while Lr uses a percentage), I find them indispensable in my work.
I have not yet found this feature in ON1 RAW prerelease, but if it exists, I hope it is available in both modes (optional) because it would tie in better with users of both Ps and Lr.
