It worked so incredibly well on the Windows Phone 7, but translated horribly to the Windows 8 desktop. Especially the weird mouse gesture to get to the neutered Settings panel, the redundancy of that panel to begin with, and the entire UWP app experience. Windows 10 was a great marriage of these two concepts, even if the Settings menu was still redundant, it was functional. Then comes along Windows 11 even it's most recent feature updates feels like a half-finished UI.
