Looks really nice, but not a big fan of the name "Power Toys" - It makes me think it's some extension to powershell or a collection of powershell scripts that does something fancy.
Well it inherits the name from the Win95 days, some years before powershell became a thing. And “power” is a word borrowed from biz like power lunches and power walking, etc. just a happy play on words.
I think it also borrows a bit from “Kai’s Power Tools”
As others have noted, PowerToys (https://en.wikipedia.org/wiki/Microsoft_PowerToys) has a long history. I have some fond memories of the TweakUI utility by Raymond Chen as it made the OS much more usable.
