Option/alt-clicking a layer's lock padlock should lock all other layers apart from that one.

Option/alt-clicking a layer's lock padlock should lock all other layers apart from that one. A further opt/alt-click would reverse the process. This would be really handy when working on a layer-heavy comp, especially when working with an effect such as Bezier Warp, where it's really easy to inadvertently select another layer when manipulating handles. Currently, option/alt-clicking the padlock does nothing different from a plain click.
