According to some reports from beta testers and other sources, WhatsApp may be getting a couple new features when their next update rolls out. The new features include a “Like” button and some ability to mark messages as unread.
One beta tester, Ilhan Pektas, tweeted out a message recently that translates roughly as, “Like Button for divided images in WhatsApp: o #cool”. Facebook has already implemented some existing features from other platforms into WhatsApp, like the “read message” tick marks found in their Messenger app that made their way over to WhatsApp. So it would not be a stretch to imagine Facebook adding a “Like” button to WhatsApp, especially in light of the role the Like button plays in their main service.
The other rumor concerning new features comes from ADSLZone and has to do with marking messages as “unread.” Being able to mark a message as unread is nothing new in technology as can be seen in virtually any email client. However, given the interactive, two-way nature of WhatsApp, that may impact how an “unread” message feature is implemented. Currently WhatsApp provides the sender with an indicator via a blue tick mark that a recipient has seen their message. If a recipient goes back and marks a message as unread, WhatsApp will need to determine whether the sender would also see that change in status or if this would just be for recipients. ADSLZone came across this information in an internal WhatsApp document discussion.
