All of mine are in same folder, and I use search or linked / unlinked panels for finding / creating links. Thousands of notes in same folder doesnt really matter if you use the Obs. provided tools to navigate it.
interesting. Thanks for sharing. I should probably give it a try and "let go" some control over the structure.
I guess I learned how my own learning and memorizing works, and managed to match it better with how Obsidian works, and now I don't have to think about silly file / folder structure anymore. Your experience maybe different.
