This announcement refers to Notebook 7 having a Table of Contents, and the User Documentation / New features in Notebook 7 section states that ‘… the Table of Contents is built-in and enabled by default’. Only, it does not seem to be. When I run Notebook 7 there is not TOC, and I can’t find any menu or toolbar button to activate it.

On the MyBinder-sourced example (click here to launch an example session), from the File menu bar at the top you select ‘View’, then ‘Left Sidebar’ > toggle on ‘Show Table of Contents’ so that is displayed.

Do you have that where you are trying?

I’d like to post a pointer to some issues I and others have been having since the upgrade to Notebook 7.0; (see also this issue related to nbclassic), which have in fact been exacerbated by the 7.0.1 upgrade. Τhey seem to apply to my homebrew install of Python 3.11 with packages installed by pip.

Short version: It seems that this combination requires explicitly setting JUPYTER_PATH=/opt/homebrew/share/jupyter JUPYTER_CONFIG_PATH=/opt/homebrew/etc/jupyter before running jupyter, although there seem to be some other specific problems with the notebook interface — i.e., lab and nbclassic work with these variables set, but notebook fails (differently in 7.0 and 7.0.1).

Are any others experiencing these issues? Are any devs aware of this and planning a fix?

Here is a quick screencast to show how to open the Table of Contents:
