Same here.

I have always thought it was super sexy to have all these panes available with an editor, logs, debugger opened at the same time ; but the reality is that I cannot work with 20 characters columns.

I use a 4k display set to HiDPI (1080 lines) and simply switch between my full-screen panes.

Sometimes I will split my tmux window vertically because I can deal with fewer lines but I never split horizontally.
