Obsidian being _just_ a UI on top of Markdown files is one of it's selling points.

That sounds exactly like Org-Mode inside Emacs.

have you heard about logseq? It seems to me that it is what you are looking for

Thanks! That looks great too. And it seems like I could actually use both at the same time on top of the same files in a complimentary fashion, though I'd have to test that out to make sure, and see if the use cases made it worthwhile.

I use todoist for basic task management, but it's ability to view history is virtually non existent so I don't bother attaching documents or anything related to a project there. But I use the API to compile task history, so I could integrate them as markdown files into this so I don't have to start from scratch in building things up.

Nope. Works on local files. Open source.

It’s one of the main reasons I went with it.

Wait. Is Obsidian open source? Any links to their code?

Definitely thought it was open source in my brain…maybe I’m wrong though.

Now I don’t actually see the code…so my mistake. At least with markdown files you don’t have to worry about accessing your notes if anything ever happened to them though.
