3: More Add-in
This tool's name doesn't do it justice. More Add-in lets you quickly and easily hide Word text by creating collapsible sections. Anyone who creates long documents comprising the same blocks of text will find this add-in useful. No more combining or merging.... just clicks! In addition, you can hide notes or any kind of content you want to include but not share. (But don't use this add-in to hide confidential data.) Or temporarily hide sections so you can print some sections and not others.
