Kind of funny that the idea of constantly flipping between a bunch of things increases productivity. I’d imagine if this person had instead limited themselves to a single 15” laptop screen their productivity would’ve increased over their baseline because they’d be focused on one thing at a time.
Honestly doubt it - I watch files/diffs side-by-side constantly - at 120 line length with a 15 inch MBP there's just no way even if I kill the explorer panel - I can just barely fit it when i zoom out one level from my comfortable font size and have the panel closed - but that's not a great experience for me.
