Eye motion has a cognitive cost. If I can take that eye motion and move it into my fingers' muscle memory to toggle screens, there is an increase in overall focus. I find an external or secondary monitor is good for large refactors across multiple repos, but that's a small slice of my typical book of work. Most of the time it's just distracting to have extra reasons to move my eyes and head. If I need a break, I go outside and look at far away things.
