> 120 character line width, set in Courier
Um, it’s not? Chrome 78 on macOS here, text is rendered in 14px Roboto, content box width is 75% (on 2560px viewport). I find it fairly pleasant to read, my only problem is page reloading on exit as I already mentioned.
Edit: The mode is gone after updating to 79, seems to be gated by a command line switch now. What the hell.
