Yeah, this is the extension of the above. Main reason tabbed windows ditched the title bar in favor of having tabs integrated into it.

Unfortunately people who design UI or produce specs are not power users so the end products have been losing utility at an incredible pace.

My personal favorite is an input field which clears its content once it loses focus. So when inputting an address on mobile you can't switch back and forth to copy different parts of it.
