"Named groups and folders of apps are no longer supported and the layout is not currently resizable" in Windows 11's start menu. This alone is enough to make me want to spring for something third-party. (The fact that existing pinned items won't migrate from Windows 10 doesn't even register, because of course they won't.)
Also, "Some icons may no longer appear in the System Tray (systray) for upgraded devices including previous customizations." What does that even mean. What are you breaking *this* time, Microsoft.
