when working with several effects such as Lift/Gamma/Gain i usefull to have a colour picker to get values under the cursor. some effects already got it but they're usefull just in niche workflows. it would be nice to have a global option to get RGB values without needing to click of move any axis. to see an example of this feature in action take a look at minute 5 in this video: https://www.lynda.com/DaVinci-Resolve-tutorials/Building-correction-when-shot-matching/160715/361836-4.html this has been discused in forum before reporting this bug: https://forum.kde.org/viewtopic.php?f=265&t=139014&p=372381 pls, give your opinions and improvements to this feature request.
