I am still looking forward for the option to ungroup task bar buttons, preferably with titles. Again! Something that was there before, worked, and was useful. But some designer decided we don't need that, to the bin with it!
A real shame, because they showed with Windows 7 that they can redesign the OS UI without giving up features from earlier versions if they want to. Bugs like "the task bar is 20 pixels taller on my second screen" wouldn't have come up if they'd stuck to restyling their old code base.
I find Microsoft's modern designs very comparable to the GNOME designs, in that they're eager to remove common features to build an overarching operating system theme. I like GNOME's design, much more than Windows 11's, but I don't think taking directions from a heavily criticised DE is the right move.
