Hey, Adobe! Why not to add a Saturation mask preset here?
It takes time to go through each color tab & manually change the values.
Certainly, we can then save it as our own preset or make an action, but why not to have it by default? 🙂
In case someone doesn't know what I'm talking about, the Saturation mask is made by changing the Black value to -100% in each color tab & to +100% in Whites, Neutrals, Blacks.
