The thing I keep sitting with is what one wants for personal knowledge management vs. collective knowledge management. I've been using athens research ( https://www.athensresearch.org/ ) so far after doing classnotes in roam thinking one there could be extensions in the future to make things 'feel' like navigating directories of markdown files if really needed.
After reading more about dendron which states on https://github.com/dendronhq/dendron "It's a personal knowledge management solution (PKM) built specifically for developers and integrates natively with IDEs like VS Code and VSCodium." , the question is how these tools could serve a wider audience if they were packaged more as standalone app (using something like Eclipse Theia).
