I was working with Adjustment Layer masks, and wanted to see before and after changes. I tried different key and mouse combos and right-clicking on the mask thumbnail, and no options to disable the mask for the Adjustment Layer, or to delete it. Could the ability to disable (or even delete) the layer mask be added. Seems pretty useful, since very frequently we like to contrast before and after changes are made.
I know a child/clipped layer mask could be added, which, being a separate layer, can be turned off and on to see before and after changes. But it seems redundant to child/clip a layer mask to an adjustment layer that has a mask already built in.
On the layer mask subject, Alt/Option clicking the thumbnail on both types of mask (separate layer & adjustment layer) brings up the mask detail view so you can see what your mask looks like, but you have to click another layer to exit that view. Minor nuisance, I suppose, but if I want to keep editing that mask, I have to click out then reselect it. Maybe just clicking the same layer anywhere other than the mask thumbnail could exit that view, or using the Esc key.
