Today, Facebook is updating Messenger with a new feature: the ability to quote and respond to specific messages in a conversation, making it easier to keep track (especially in larger group chats ), as indicated by VentureBeat.
This feature is an extension of the company's existing response, emoji. From now on, when you hold your finger on an individual message, in addition to simply adding a reaction, you will be able to respond with a new "Reply" button, which will attach a quoted version of the original message to your answer. The messages cited are not really their own message threads – they will always appear in alignment with the rest of the chat, but that sounds pretty useful.
It's a pretty simple feature that WhatsApp, a Facebook-owned email application, has been offering for quite some time. It is therefore logical that Facebook brings it to Messenger. This decision also ties in with the company's global ambition to create a cross-platform system that would unite Messenger, WhatsApp and Instagram messaging. Obtaining comparable functionality on all three platforms would definitely facilitate the eventual merger.
