Feel free to accept the PR, take parts of it, get inspired by it, or ignore it entirely, whatever you like :D

@steveruizok FYI, updated the PR to include a few more additions.

No pressure to accept or even look at it, just happy to add to the project!

Also please let me know if you do not want pings, I'll respect that of course.
