I also prefer my prompt to stay at a fixed position. However, having
command output *below* prompt is not a good idea. I've listed a few
reasons in https://github.com/romkatv/powerlevel10k-media/issues/2#issuecomment-725415740.
What I do instead is put prompt *at the bottom* and make it stay
there. The latter is a bit tricky because completion listings can push
prompt up. With a bit of work this can be changed so that completion
listings appear above prompt in a sort of temporary overlay. This
setup is quite ergonomic as it allows you to position your terminal
window so that important information (prompt and the end of the output
of the last command) is always at the same position. You can see it in
action here: https://asciinema.org/a/372068. You can also try it in
docker: https://github.com/romkatv/zsh4humans/tree/v5#try-it-in-docker.
