Go Launcher and Go Locker

I have installed these two apps since they are my favourite ones and are very customisable and skinnable.

Only problem is their default install now has a lot of advertising so best thing is to delete all the home screens and start new.

They are installed on the data folder so feel free to replace them with your own preferred launcher/locker.

Just remember not to move the launcher or locker themes to your SD card as they may not work properly after reboot. (especially locker themes)

With GO Locker installed the home button will skip the lock screen and go straight to Home.

To fix this open GO Locker, go into the Settings, choose Home Key Settings, enable Home Locked and follow the instructions.

The Home button will then correctly go to the lock screen from a power off state.

You should also select option Turn off system lock to avoid two lock screens appearing.
