So a semi-related thing I've been casually thinking about recently is how to develop what basically amounts to a hand-written programming language.

Like a lot of other people I make to-do lists and take detailed notes, and I'd like to develop a written notation that not only captures basic tasks, but maybe also simple representations of the knowledge/emotional states of other people (i.e. employees).

More advanced than that, I've also been trying to think of ways I can take notes in a physical book that will allow a third party to make Anki flashcards or evernote entries based on my script. It has to be extremely dense to fit in the margins of a book, and must capture distinct commands like "make a single cloze deletion card for this sentence" and "make four separate cards for this sentence, cloze deleting a different piece of information for each card but otherwise leaving everything intact" and so on.

Any thoughts?
