Any plan to add this package to MELPA?

It would be nice to add this package to a package archive such as MELPA.

I can't answer the question, but for now I found it easy to add this package with use-package and straight:

(use-package outli
  :straight (:host github :repo "jdtsmith/outli"))

I am considering adding to ELPA, as it mostly just configures outline-minor-mode and adds org quick bindings. Any suggestions for improvements before then?

Any suggestions for improvements before then?

my opinion is to always release what's there instead of waiting for more: adding one last thing before releasing is a good recipe to never release :-). MELPA maintainers requires you to lint your code base so I would focus on that.
