Am I missing something? I don't see any options in the backup reset menu other than restore preferences.
Go to settings, battery, there are low battery settings and battery icon .
On your quick pull down settings, you Could select location settings, wifi and wifi ap settings..
There are quite some necessary settings/customization hidden here and there, when you use it, you know it.
PA does not have a separate tap in settings for customization. It is involved in the system whenever needed. You could reset all preference in the backup and restore settings.
PA is going on a more closed to stock and less intrusive way on its philosophy, which I do appreciate and admire a lot.
If it's not your style, there are some other good roms in xda. You might give them a try.
