Button to expand / close all hidden cells

[kolibril13]

Context

Hidden cells are great to keep the notebook concise. But they also reduce code accessibility, and the click-to-reveal interaction requires lots of clicking when there are multiple cells with a hide-input tag.

Proposal

My idea is a button to expand / close all hidden cells. Another option could be a keyboard shortcut. This would allow users to quickly switch between the detailed view and the concise view, similar to zooming in and zooming out.
