How Do I Hide Comments

When you, or your collaborators, comment on a document, their comment will appear on the side of the document. To hide comments, just click the menu button at the top right of the page. 

From here, a drop down menu will appear. Select Hide Comments. 

This will hide the comments but leave behind dot marks where notes have been made. You can hover the cursor over these to show the comments that have been made at that point.
