> On my 32" 4K display, 70% of the screen is empty. Totally agreed on your other points (particularly about animations on selection) but as the article mentions, eye tracking repeatedly shows people have trouble reading very wide text. Also many people use large monitors to have multiple windows, rather than a single window maximised.
I stopped maximizing my browser window a long time ago, and I only have a 27" monitor. It's just not comfortable for me.
I've noticed also that I don't like to read text that starts on the left of the screen.
The solution that works for me is to install a sidebar (on Firefox, AiOS add-on) and if text is too wide or starts too much on the left, I enable and resize sidebar accordingly :)
