It also includes tools that change day-to-day behavior, like enforcing picture-in-picture for apps that don’t expose it, enabling multiple audio streams at once, and giving per-app audio controls beyond what Android typically allows. For power users and automation fans, it offers shells that can execute raw ADB-style commands directly, including an intent-driven mode designed to be triggered by automation apps like Tasker or MacroDroid. -
