WhatsApp, the most popular IM app is currently testing a new feature by which you can Pin chats if you want. All of us who use WhatsApp know that group chats + individual chats make it difficult for us to find the chat that we want to get back on. Often we have to scroll or search the chat for a significant amount of time to get to our desired chat which is not that user-friendly. So to make things easier WhatsApp has built the Pin feature which will let you pin chats. The Pinned chats will always remain on the top so you don’t have to spend much time for searching it and get your hands back on your favorite chat anytime you want. The feature is currently in beta version and soon it will be rolled out on stable releases as well. Whatsapp will let you Pin three chats and then if you want to Pin after three chats it will give you warning that you have already pinned three chats.
To Pin the chat you want, you have to pick the chat from your conversation list and hold on it until options appear. In options, you will find Pin as well as Archive, Delete and Mute. If you are running Whatsapp beta version 2.17.162 or 2.17.163 then you can use the feature right now or you can wait till it comes in the stable version.
