It would be great to have a mechanism (or API?) to expand and pin every section in a notebook.

As [others have pointed out](https://twitter.com/driven_by_data/status/1049720375540703233?s=20), [bl.ocks.org](http://bl.ocks.org) makes it easy to see all the code immediately. On Observable, one has to manually expand and pin each section.

Has there been any discussion of a mechanism to expand/pin everything? Maybe a URL param?

Thanks

There have been a few such requests, e.g. [Is there a way to "edit all" or "pin all"?](https://talk.observablehq.com/t/is-there-a-way-to-edit-all-or-pin-all/893) and [Via UX prompt: Ctrl-F to find code in someone's notebook](https://talk.observablehq.com/t/via-ux-prompt-ctrl-f-to-find-code-in-someones-notebook/1460/4)

The suggested workaround for now is to open a separate tab/window in safe mode (add `/safe` to the end of the notebook URL). The notebook will update simultaneously in all open editor instances (provided your internet connection remains stable).

I just wanted to chime in to say that with Broadcast Channels:

You also have a pretty easy way to synchronize local state between the same notebook open in multiple tabs or windows. It makes it even easier to edit a notebook and tweak sliders in one place, while keeping the output consistent and never needing to refresh…
