Yes, most of the time you only need one screen, two screens mostly generate distractions. But I have noticed that switching workspaces is a context switch for your brain, just like passing through a door. You often forget what you were doing right after leaving a room for that reason. And when I truly need two different windows in a shared context, like some documentation in the browser and my code editor, it saves effort to have them truly side-by-side.
