The Preferences editor allows a certain amount of hacking app data on the fly. View, find and modify the clone’s internal app settings and enjoy creating some pranks. You can find it in the pop-up menu under the Installed clones tab.
Note that not all apps store their settings in preferences. Games often store game state and settings online. Apps may also store settings in databases; here you can try the App Cloner Database editor option. Sometimes preferences are also encrypted, making it impossible to modify their values.
