A new Twitter tab marked "Explore" has squeezed its way between Home and Notifications in the microblogging website's mobile app. When it makes its way to your device, that's where you'll have to go to find Twitter's trending topics, Moments, search and any featured live video. In fact, it completely replaces the Moments tab if you have it in your app. While you could find those features through other means, Explore was designed to make searching for trends, popular topics and the latest news much easier.
