WhatsApp has just added an interesting new feature: Keep in Chat, which enables you to save a message so you can refer back to it in the future. It's a handy way to keep little bits of information (or just funny stuff) from chats that might otherwise disappear, and it doesn't get in the way of the sender's privacy preferences. That's because WhatsApp has also decided to give the sender the opportunity to veto any Keep in Chat saves.
According to WhatsApp, the feature – which is rolling out globally over the next few weeks – is really straightforward: when someone keeps a message from a chat you're expecting to disappear, you'll be asked if that's okay. If it is, great: the other person can save your message. But if it's not okay, you can override the request.
