If my Easter break gets boring I might just start cleaning up that Python library... It's the prime example of something that developed from a POC to a fully functional code base, was left largely unused for about a year, and just the past weeks has suddenly seen a lot of use again. Luckily we're strict about good docstrings, but type hints would have been nice too.
Woo, do it! And add some tests while you're at it in case those don't exist.
I found a few bugs just going through and cleaning up missing code coverage. Maybe you'll find the same!
