Apparently, Whatsapp will soon introduce a new feature soon, called Read Later. According to WABetaInfo, this feature is an improvised version to the existing Archive Chats feature of the app. It allows users to send messages directly to the Read Later category. The users will also have an option to disable this feature in chat settings.
WABetaInfo also reported that Whatsapp wants to reduce the interruption as the messages under the Read Later tab will not come up with any new notifications. This feature will be available to users in a few weeks. WABetaInfo is a Twitter account which tracks the new builds of Whatsapp application.
