If you use emojis to react to messages at work, you can now do that with Google Docs. When you highlight the text you're commenting on, you can now “Add comment,” “Suggest edits,” or “Add emoji reactions.” There is now a new button on the bottom-right corner that gives you the picker for emojis. If someone left an emoji you agree with, you can just tap the emoji to add on. This feature is rolling out on the web in the coming weeks.
