I illustrate in photoshop by painting within Solid Color layers, instead of standard layers. I therefore paint withing the layer mask, not the layer itself. This gives me the benefit of being able to change colors of layers very easily, and mimmics a vector workflow within Photoshop - at least as far as color and layer management is concerned. This is wonderful for very complex illustrsations. My feature request is that the move tool's (crtl or command) selection feature should also offer the option to select layer masks, not just layers or groups.
This simple addition would make the process of working with solid color layers way faster. It would make Photoshop behave much like Procreate. And the only thing I like about Procreate is that the color and layers act like solids. Thanks!
