I really hate that change. It's counterintuitive that a shell recognizes mouse clicks to mean "select this option".

Also, the auto-copy selected text feature is awful. That's another thing that is so counterintuitive. I have never seen a UI where just selecting text means auto-copy to the paste buffer. Who is coming up with these awful UX ideas?

On top of that, the scroll "feel" of the new client (at least on macOS) isn't quite as good as their old one. It just feels off and not like a native terminal.
