This would be even cooler if there was some heuristic to prefer codes based off of the titles somehow. Like if math-5/limits could somehow get the code M5-LM. I wonder if this is even possible to implement consistently at all. Sounds like a fun problem to solve (it’s the kind of thing an LLM could probably do very inefficiently)

Could probably be done by using the path of your note. You could manually specify the code for directories (such as M5 for math-5) and subsequent codes could be based on that. Your code would then be {dir code}-{random letters original to the note}.

Directory codes could also be nested with this

I think Obsidian's fuzzy search already kind of works like that, but that's a really cool idea for generating codes.
