I am writing a textbook where I want to reference a bunch of observable notebooks, some that I wrote myself, other notebooks written by other people.
Now, say that I reference a notebook that has a number of imports from other notebooks. Is there a way to keep the notebooks and dependencies in a frozen state? I worry that some imported functions may disappear if their creators just takes down the notebooks. I can of course fork notebooks, but it will be a hassle to also fork all dependencies. Hope this makes sense.
