I got around the `tmux` barrier by writing down my most useful commands on an index paper, cutting it into the smallest rectangle I could (and folding in half), and tucking it in the pocket of my phone's flipcase (or you could stick it inbetween your smartphone and its back-shell). I'm pretty happy I got over that hurdle.
