Q: I can’t find developer options, why?
A: Settings -> About tablet -> Click ‘Build number’ several times

Q: I don’t have reboot options in power menu, why?
A: Settings -> Developer options -> Advanced reboot

Q: I have no root, why? What is that hashtag on my status bar?
A: Settings -> Developer options -> Root access. Root management is now integrated as part of CM’s Privacy Guard and you can manage per app permissions under Settings -> Privacy -> Privacy Guard. You’ll have a persistent notification in the status bar when you’re running an app that uses root permissions.
