Updated version of VR25's Magisk Manager for Recovery mode. Works with Magisk v19.0 - v26.X! With this you can be at ease while trying out Android Magisk Modules. Since if you end up with a bootloop, you can just disable the module from recovery! Saved me many times! This app is used in a recovery terminal (e.g. TWRP), not in Magisk itself.
