the new commenting features.
Google Docs, Slides, and Sheets for iOS and Android now have instant mentions in comments. Simply start typing a contact's name in a comment box and you will see a list of suggested names to mention in your comments. Anyone you select from that list will be notified of being mentioned in your comment.
One of my favorite features of Google Docs comments is the ability to reply to someone else's comment. Now you can do that in the Google Docs, Slides, and Sheets mobile apps too. And to make it easier to sort through comments all of the Docs, Slides, and Sheets apps have comment swiping enabled.
Applications for Education
The latest updates to the Google Docs, Slides, and Sheets mobile apps bring the experience on a tablet closer to that of using Docs, Slides, and Sheets in your web browser. For schools that have BYOD programs these updates should help streamline your workflow throughout the Google Apps suite.
