Today I present to you multiuser support for our Z1 on .108 firmware!
Superuser mod (not sure if that's needed, but better be safe than sorry)
Additionally I made the minimum screen brightness even lower than stock as it was a bit too bright for me at night.
Just flash the zip in recovery and reboot. If you want to test it on some other firmware or device then make sure to make a backup!
Restored the navbar
I'd like to thank my friend Dominik Lisiecki that basically made it happen as he did all of the compiling and recompiling for me as I have no access to the PC now.
Dzięki stary, jak wspominałem - stawiam ci browara. :P
