Would be a very nice feature indeed, but might be out of the scope of this project.

When I wrote my first PR for this project, I also implemented a POF "cmdline history system".
It was quite a fun but also relatively complex challenge, and I decided against submitting a PR.
You can check it out here: https://github.com/haruInDisguise/code_scratch/blob/main/cmdline_history/main.c
Just clone the repo, cd into cmdline_history, run make and execute main. This assumes that you are using a linux environment with basic devtools.
I've tried to comment as much as possible, and I included a little "abstract", explaining the issue, but if anything is unclear, just ask :)

It could make sense, to rewrite this project as a small librar. This would conflict with the idea, that this project should stay clean of external dependencies (which I personally like a lot) or as you put it "It might be out of the scope of this project".
