"Color to alpha" button

[dolldivine]

A feature request for Photoshop to catch up with the rest of the world and add a "color to alpha" toggle like GIMP and Krita have.

A menu would pop up where you can select a hex code (similar to Replace a Color).  Wherever this color is found would become transparent, and where it's partially found, it would become partially transparent.  Maybe a fuzziness toggle.

See extensive discussion about this here:

I have been looking for this function in Photoshop for about ten years and it seems to be pretty much impossible to do it perfectly. The other downside is that most discussions online do not understand the required function. Why does this function not already exist, and if it doesn what it is called, I aM gOiNg MaDdd
