The visual revamp isn't a huge surprise given how keen Google is for developers to embrace Material Design and its various principles. What is notable (but no less surprising) is the placement of Moments inside the new app. The feature is truly front and center now -- an attempt by Twitter, no doubt, to make the news-centric hub more popular with users. What was once known as "Project Lightning" has had little effect on Twitter's stagnant user numbers, but CEO Jack Dorsey will be hoping that can change now that it holds such a prominent place in the Android app.
