Presently the default width of the content in the Document reader is the narrow view. This results in wider content like tables to have horizontal scrolling.
In order to avoid this, the following suggestions can be taken into account -
Change the default width to 'full-width' or at least make it configurable
Move the width switcher to the top bar to increase visibility and accessibility.
This will definitely help our adoption as people don’t use the document view due to large content being incompatible with fixed width. Despite being told they can disable it or go full screen.
