Even if you [[id:ea263f6f-fa8e-4e6d-a585-d30d493d1e3c][Add a desktop search engine for your digital library]] and know the structure, it's not always worth with the overwhelming pile that will accumulate further since you always navigate certain notes through a fixed path.
Similar to certain software projects like Xorg, Rust language, magit, and org-roam, there will be a point where you have to redesign them. [fn:: Xorg has Wayland as the successor, the Rust community can revise the language freely through editions, magit did have a crownfunding campaign to pay the developer to rewrite it for a year, and org-roam is recently through a major redesign.]
They should eventually evolve into [[id:431532c3-6506-4565-b193-dbfb60eac7d6][Evergreen notes]], branching out of the original notes structure and making a better graph for navigation.
