I am writing documentation for a notebook-based framework. When referring to important cells in a demo-notebook, can I point to a particular cell by using some sort of anchor?>
Not on stable, and only on Header(1-6) cell on master. Just click on the header cell and it will put the right anchor in the url bar, wich is usually #header_title_sanitized
Using the prompt number is not a good idea as it might change. It will be supported on nbviewer as well, we are working on it.
