Moved on to dark patterns and dumbed down interfaces. Personally, I really miss mnemonics. Alt+underlined letter for_everything_. But having an underlined letter for everything died out and keyboard nav means a lot more memorization.
I'm going to miss when the ability to double-click the top-left corner of a window will close it (and right-click brings up the window menu). This has been around since the Windows 3 days and still persists in 11, but it's going away in some places - e.g. you can't do this in most browsers, and the new file Explorer in 11 dropped it to support tabs.
