Hi, is there any way to increase the page size in the Navigation pane?
The preview of pages in the second tab of the Navigation pane in MS Word.

I know of no way.
You can widen the Navigation Pane, but that does not make the thumbnails bigger.


Note, use built-in Heading Styles.

p.s. It is seldom that I use the pages tab.
