hut, 
What do you think about my project #panban?
https://codeberg.org/hut/panban
It's a #kanban board for all kinds of data backends (hence the "pan").
Looks a bit like #ranger, but for multi-column todo lists.
You can currently use it for #CalDav TODO entries, #markdown lists, #todotxt files, and a read-only view on GitHub issues.
It's great in combo with #TasksOrg [https://tasks.org].
Been using it a lot over the last 5 years, tho it's still experimental. Thinking of rewriting in #rust.
