Especially for long documents it would be nice to have the possibility to toggle the document paragraphs as Microsoft word already does.

Basically a double click or a click on a dedicated arrow should show/hide all the contents of the Heading.

If I click on an heading 1 all the heading 2, 3, 4 and related texts should be hidden in the document; if I click on a heading 2 only related H3, H4 and text will be toggled on/off, and so on for H3 and H4.

It will allow to have a much better readability for long documents.
