Please add a Heads Up Display (HUD) of Color Values next to the Eyedropper/Sampler cursor while moving the cursor over an image to measure values instead of the values displayed in the Info palette. This would be a huge additional feature!
Typically I use Track Actual Color Values. I usually work in RGB and CMYK modes in 8 bit. I do quite a bit of product matching also which is why I am requesting this feature. To have the option to toggle this proposed feature on/off would be cool since some users may not like to have this active all the time.
I hope this answers your question.
BTW, I used to beta test Alias Eclipse software (running on Silicon Graphics hardware) and offer feedback to Alias in the early 90's. It was very rewarding to be a part of the development stages.
