For example, in Windows 11 I spent close to a minute looking for "Rename" in the right-click menu in Windows Explorer. Turns out it's not there! It's been removed out of the flow of the list and put in the top of the right-click menu, behind a small, picture-only icon that I've never seen before.
MacOS is guilty of this too: Buttons along the top of native apps like Finder don't have text anymore, the buttons are flat without borders, and the icons are thin lines. How is anyone supposed to know what they do??
In most UIs (Apple and Android in particular), I can't tell when one of those on-off switches is ON or OFF. Is the dark side ON or OFF? Maybe the light side is ON. Oh, it's the opposite when Dark Mode is enabled; great.
Bring back text. Bring back nice buttons.
