For anyone who's rooted their Android phone or tablet, the SuperUser app is a familiar and friendly face. If you don't know what it is, it's that "Droid and crossbones" menu that pops up to allow you to confirm or deny root permissions. After several years as the de facto standard, one XDA member named Chainfire aims to dethrone it with a much-improved application, SuperSU. (Yes, that stands for "Super SuperUser".) The free and paid app adds a bevvy of new features for advanced users, and it's available on the Google Play Store right now.
