I use ClickUp[1] in similar ways. I have three spaces: family, personal development, professional development. All of the side projects I have are under personal development, various work commitments (including e.g. rental house management) under professional, and family varies from "scoop the litter box Mon/Wed/Sat" all the way to 10 year goals. I have not (and may not) reach steady-state on the way it's organized, and I may end up splitting some of it off into a dead tree some day, but for now it's accessible, consistent and actionable.

I'm surprised I don't hear more about ClickUp on HN. Generous free tier, can share lists with other people, support for automations...
