If you want to send emoji reactions to someone you're chatting with on Google's Messages app, it's now possible to do that, even when you're on the web. Google updated its web client to allow you to send emoji feedback. You simply need to hover over any message you want to reply to, and two new icons will appear. One with an emoji, and another is an overflow options button.
You can choose from seven reactions: thumbs-up, heart eyes, laughing with tears, surprised, sad, angry, and thumbs-down. It works on your messages and anyone else you're talking to, including group chats. But you can only send one reaction per message. The feature is rolling out to everyone, so it should make its way to you soon.
