The article I read said it would be included in ver. 0.84.0. We're on 0.83.0 now, so I would guess very soon. PowerToys is a very powerful utility and the design, using modules, is unique. Some of the modules I use everyday are FancyZones, Keyboard Manager, Mouse Pointer Crosshairs, and Color Picker.
I agree that this looks very good. You can kind of do this now using the Windows settings in Sign-in Options, but only one setup.
Thanks for the reference.
