The good news for those who chat a lot using Facebook Messenger, it seems that Facebook has started to roll out an update to the app that will introduce threaded replies. This means that it will function similar to WhatsApp, where you can long press on a message and you should see the option to reply.
When you press that, you will see the message quoted and when you send your message, it will be included with the quote so that the user knows what you’re talking about. The feature is rolling out as we speak so you should be able to see the feature available shortly. If not, don’t worry as we imagine that it shouldn’t take too long before it is rolled out to all users.
Note that this is only for the Facebook Messenger app on mobile, which means that if you use the desktop version of Messenger to chat, you won’t be seeing that feature, at least for now.
