Facebook recently added new feature called message replies and it allows users to reply specifically to one message without filling up the full message thread. Here’s how it works, when you see one message as you wish to reply on, simply long-press on a message and tap the new reply icon. From there, your response will be sent and directly attached to the original message. You also can do that with GIFs, videos, images, and emoji too. It’s kind of easier to keep track of who’s messaging to who in a busy group chat.
