Thanks for the compilation! Yes, it's a very small and helpful simple idea.
However, none of the projects you linked is a combination of 100% shell & the UX I was looking for, which is a reason why I've decided to share mine.
That's a good suggestion. I've been using it quite a bit and sometimes editing the output before running would be handy. Although in these cases typing it out or copying+pasting isn't too bad, and still keeps my focus on the terminal rather than in a web search.
That being said, I'll consider adding the edit feature, thanks for checking it out!
