For me you're correct -- I too limit distractions but I also literally get tired several times quicker if I have to read / write on a 13" or even MacBook Pro's 15.6" screen. I have a 27" iMac Pro and I almost never use any splitting -- except for my editor where having 2 panes side by side is very useful and I still get 95 characters per line on each pane. ...Lately however I felt like I need a bit more space so I ordered toughened display stands (both the iMac Pro and my gaming 35" display are 10kg or more) so I can likely move all my web browsing and Slack itself there, side by side, on that second gaming screen. Still not sure how will that turn out though, I might not need it.
