Very interesting. Seems inspired by Luhmann’s Zettelkasten.
Though I’m disappointed by the fact that the code changes every time a note is renamed or changes location. It’d be wonderful if the code assigned to a note would be immutable. Could this be added? (There’s a long-standing feature request for this to be added to Obsidian.)
There’s also a matter of future-proofing. I would be very cautious to become reliant on such a plugin: a future Obsidian update could break the plugin’s URL scheme, and/or the plugin could stop being maintained.
