My partner and I use a pinned issue as our grocery list on our git repo for managing our household. All running on top of a self-hosted gitea instance.
Great for being able to create git issues for honey-dos as well as having automations for creating issues for recurring tasks.
“Hey we need to take X to the vet for Y sometime next week” “Oh yeah, can you go ahead and put in a ticket?” Amd vice versa
