Twitter has a Lists feature that let you keep specific people or accounts you want to follow in one place. However, this list doesn’t show up on your timeline. Twitter wants to make it easier for you to keep track of your favorites with a new “Fave People” timeline. The social network is testing out the new feature on Android. The timeline will appear beside the main timeline on Android app. It is currently available on the alpha version of Twitter’s Android app so there is no way of telling at the moment if it will be available on other platforms.
