Color picker when painting rough/height/metal/normal/AO channels instead of slider only.
It would be great to be able to pick the information seen in 3d viewport instead of always having to guess which float it could be that fits a certain greyscale/red/green/blue on the model, jus as it is possible with the basecolor information.
This is what I´d like to be able to do: lets say I am looking at roughness or height channel. I want to pick a certain greyscale or red/green tone which i can see in my viewport to fit a certain roughness or height on a certain spot on my model...without having to use the slider and guess which value between 0-1 it might be...just like I do when picking a color in the base color channel.

One should be able to pick from whatever channel you see in your viewport. When wanting to make transitions or adding information to height ..or continuing your roughness in the exact same value you see on a certain spot on your model... Always asked myself why there is no color picker when working on other channels than diffuse... By now I jus have to adjust the slider, having to guess, until it fits the greyscale or red/green I want.
