"GravityBox has been, for years, one of the most popular Xposed module out there. The Xposed Framework, in case you’re unaware, is one of the most powerful tools used by Android modders. It lets modules modify the code of other apps before, during, or after execution, giving you total control over all the system and user apps on your device. It opens a lot of doors up for new ways to customize your phone, and while it may not be as popular or as widely used as it once was, it is still in use even today"
