Automagic Forum

When I uninstall and reinstall AM, I have to resetting the preferences. And also re-add all widgets in the home screen.

Is it good to store preferences as .xml ? Then we can send the preferences to the other users too.

I'll add it to the todo-list to store/restore settings. However, it will not be possible to store/restore all settings since some settings like Device admin functions, Accessibility service, Access to notifications have to be enabled on the system by confirming some dialogs etc.
Widgets on the home screen are handled by the launcher app so it's in general not possible for Automagic to restore the widgets on the home screen.
