The pre-requisites are straightforward - your phone needs to be rooted, you need to install the Xposed Framework and you need to install and enable the MoDaCo Toolkit Xposed module.
Once you've done that, load up the MoDaCo Toolkit and click the 'Google Nexus (all)' section. Click 'Show users on power menu', reboot your device and you're done. Easy eh?
Now that multi user support is enabled, you need to know how to add and switch users. You can add users via the 'Users' menu that now appears in 'Settings'.
You can switch users by pressing and holding the power button and selecting the name of the user you want to switch to. Simple!
Now, I know this works on the Nexus 4, but if you try it on another 4.2 device, please do let me know how you get on!
