Commenting and Proofing Feature
When improving the commenting and proofing feature it would be nice to have additional features similar to what is found in Adobe Reader, such as the underline, strikethrough, add note to replace text, and insert tools. These make editing large bodies of text easier and clearer for all parties involved.
@Heather Welcome to the forums! Cait's post is around Proofing comments too and it might be an interesting one to look at and upvote.
