Other than that, org-mode can also be your postman, but mixes well with your other notes. :)
it's got nothing to do with tmux/vim/zsh, instead, it's an example of emacs's org's polylingualness showing just how sweet it can be when extended to support one of 'any' console tool you care about, in whatever workflow.
you make these documents with notes, and run them or any part of them from org or tangled/driven from the commandline. its nice. plus the editor ...
#+begin_src bash :results verbatim
: "userId": 1,
: "id": 1,
: "title": "delectus aut autem",
: "completed": false
Edit: Found it: https://orgmode.org/worg/org-contrib/babel/examples/fontify-...
And I have a pretty vanilla doom emacs config.
