I&#x27;ve been using some form of tiling manager for 4+ years now (herbstluftwm at the moment, though with stints using i3, awesome, dwm, bspwm and xmonad) and I&#x27;ve never had a problem with lines over 80 characters. I tend to use small font sizes, but I can&#x27;t recall ever getting into a situation where 100 character lines were an issue. I can&#x27;t recall any of the mangers I&#x27;ve used having a key combo to open up an 80 character wide terminal, though I could be forgetting.
