This idea is for Photoshop on the Desktop.
It would be great if there was a right-click context menu option to toggle individual Layer Thumbnails on/off. When documents contain many layers, it could be useful to hide certain layer thumbnails that are not important while leaving other, important thumbnails visible. For multiple layers, grouping them into a folder would work. However, if the stacking order doesn't permit that or logic precludes doing so, we're left with putting one layer into a folder to collapse it's thumbnail. This seems counterintuitive.
Thanks for your time and consideration.
