Launchers are heaven-sent because they make browsing and sifting through all those Android apps easier. You know how hard it is to locate that one app you really need especially if you have tons of pages of all apps that you don't actually use. That's why launchers are needed because they show the apps you frequently use quickly especially when you need them right away. Yahoo Aviate Launcher is one app for Android that brings relevant information to the user. It was recently updated to include a special feature called Smart Stream.
