I found some scattered comments here and there about desire to see layers/masking added at some point in the future, but I figured it deserved its own thread. My use case workflow is editing real estate photos, where I create layers where I edit for a distinct part of the image in each layer, and finally assemble/mix the final image by masking and blending each layer appropriately.
The editing itself covers my needs pretty well, but I'd be super excited and promptly cancel my Photoshop subscription when/if support for layers/masks is added.
Best,
Michael
