This is my personal todo app, which I made a while back after the original https://xit.jotaen.net/ post. tuido is written in go, with the bubbletea tui framework.
My daily workflow involves creating YYYY-MM-DD.md and taking notes, many of which are effectively low-level todos that fall below the threshold for more public or involved issue trackers. Problem was that these half-hazard todos weren't tracked at all.
After seeing the [x]it spec, it seemed clear that a little tooling could fix this. I've been reasonably happy with it.
