I was assigned a big project at work 2 years ago. Apart from main code base there were a bunch of other modules and services it talked to at it was all very old code. I couldn't have kept all of that in my head throughout.
I kind of rediscovered OneNote which helped me actually do the project. It's like your thought dumping playground. It's the only tool that offers least resistance to jotting down thoughts in whatever form you like. Every page is like a freeform infinite canvas. Just click anywhere, start typing or paste the screenshot or even files.
OneNote has been my daily driver since then. I mostly just dump thoughts in a lossely structured system that I am following for myself.
Same here though my preferred tool is OmniOutliner or any similar tool with hierarchical branching. There are other tools like Roam/Obsidian but Omni has proved to the fastest offline local macOS app with the most rich feature set.
