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}.
Better still, the chats between Danish PM Mette Frederiksen and other members of government concerning the (possibly illegal) culling of all mink in Denmark.

I used to read paperbacks a lot. Now, I almost exclusively read on my Boox Tab Ultra, which I got used for ~300€. It's rather expensive when compared to regular eInk devices, but I feel that it is worth it for me to be able to take notes in the margin with the physical pencil that comes with it - just as I used to do in physical books.
That being said, given that high quality eInk readers can last for many years, it has come out cheaper for me to get this rather expensive device when factoring in the price of ebooks vs physical books. Also, I read a lot of literature in the public domain, which is of course entirely free to download.
