It used to be that I could point to aspects of native Windows UI, like how Win32 handled mnemonics in menus, and ask developers to replicate it to make their apps more accessible.
With the constant regressions and pointless redesign in Windows 11, and the fact that those two are often indistinguishable from one another, that's becoming less and less palatable.
If a web app has an inefficient menu implementation, it's hard to say whether adopting whatever nonsense Microsoft is breaking this week would make it better.
