For years, I've been using the fact that adding a mask to a layer woiuld mean that that mask would be included in the png when I use Quick Export as PNG. Working in Game development this has been part of my workflow for years, enabling me to quickly export many assets in one go at Power of 2 sizes even if the image data itself was not Po2.
Through the grapevine I heard that this was found by Adobe as a bug, and it has been "fixed", but this means that now, instead of a single click to export all assets in a file at the required size for export (good for compression in game engines!) I have to Save As Copy for each individual layer which significantly increases my workload just to save my exported assets.
Can we please bring this back, or at least re-add the option to use legacy export, which has also recently disappeared.
