We'll probably open-source it at some point but its still a work in progress. A lot of the code is shamelessly borrowed from ITFlow.
Honestly, @johnny and I have had a million conversations about task tracking tools. We've discussed Github issues, Redmine, Nextcloud decks, Trac, etc. I feel like I've demo'ed almost every tool out there, but we could never find one that fit quite how we wanted… So we decided to just write our own (Johnny did all the work, mainly on new years I might add).
