One of the main advantages of using Jupyter is the ability to code and document in the same time. Many times, I use headings and subheadings to group the code in a notebook. However, as the notebook gets longer, navigation becomes much harder.
It would be nice to have a document map in a separate (left) pane that keeps track of the markdown headings. Once a heading is selected in the document map, the respective section would appear in the main pane.
Is there an extension for this task?
