Windows 11 is miles better than 10, but it's still a hot mess. Here's a couple of windows I just pulled up to illustrate.

Can't even get all the windows to the same light/dark mode let alone have a unified look of components. Variety of title bars, different checkboxes, different fonts, colours even the way window navigation works differs in jarring ways within areas like control panel (sometimes opens new window, sometimes uses current, sometimes current but with sublevel logic).

Maybe I'm just sensitive to this sort of thing, but unified is certainly not a word I'd apply.
