Big changes are headed for Snapchat — again. The company is set to roll out a major redesign of its app in the coming days, Snapchat confirmed Thursday. The new look, which is being previewed to the company's beta testers on Android now, adds a search bar, new navigation and a global live story that will feature snaps from all over the world. The new look is much more polished than previous versions of the app and the search bar makes content much easier to find.
