How it works: You hold a key on your keyboard and click on a checkbox in the layers window. When clicked all layers except for the layer you've clicked get disabled. When you click on a layer which is the only layer that is enabled it toggles all layers on again using the same keybinding. Example: "alt+[checkbox]", "ctrl+[checkbox]. Why: Paint.net is simple, i get that. But this shortcut could save someone like me a lot of time when showing some UI concept arts or something like that.
