WhatsApp Like - All you want to know

WhatsApp Like: 

According to reports from WhatsApp beta tester Ilhan Pektas, the WhatsApp service could soon feature a 'Like' button.

This would allow users to give the thumbs up to content posted on the app.

The 'Like' button could also allow you to send a short reply to simple messages and help communicate more quickly in group chats. It might also help to show the popularity of a WhatsApp message.

Mark as unread in WhatsApp:

Another possible feature coming to WhatsApp is a “Mark as unread” option, which would work in a similar way to your email.

After you have read a WhatsApp message, you could mark it as unread so that the notification again shows and probably the blue tick might turn back to grey tick in WhatsApp.
