Please add numbers back to the comment bubbles in the document margin. In Word 2010 (and earlier, I believe), the comments in a document were numbered in the Print Layout view. This feature was removed in Word 2013. Please reinstate. It's very helpful to ask someone to review a specific comment number, particularly when a document contains a lot of comments. It's better than telling someone to review comment 4 on page 55, because page rendering changes somewhat from computer to computer, and if someone makes any revisions, the page number of the comment may change.
