Personally, I like the Getting Things Done method, which has you store notes in an "inbox" (for me, that's a Trello board), which you prune daily or weekly, which involves pruning out the stuff that really isn't important or that can just be done right then. Once I deem a thought or some information worthy of long term storage, I use the mind mapping software TheBrain. That allows me to store information quickly... Source: 7 months ago

Works really great! Also, I'm a 20-year user of TheBrain (thebrain.com), and I can drag and drop the files from my Obsidian vault to TB as links. Then, I can edit those files in TB, link them to other 12,000+ thoughts in my TB, and those edits will show up in Obsidian; vice versa, edits made in Obsidian show up in TB. Source: about 1 year ago

In this type of programs the best is theBrain https://thebrain.com/. Its dynamic mind maps allow store any quantity of information there. Source: over 2 years ago

I use https://planka.app/ and I love it. Source: 7 months ago

Planka is like trello, but free, self-hosted, with unlimited everything (boards, users, ...). It's fairly easy to uninstall, as well. Highly recommended! Source: about 1 year ago

You should check out Planka (https://planka.app/ ). Source: over 1 year ago

I think Mealie, Planka, and AgenDAV (backend)/Sabre (frontend) would allow you to do all those things self-hosted, albeit not all in one place. Source: over 1 year ago

I use the builtin issue board in Gitea, but https://planka.app/ is another good option. Source: over 1 year ago
