I am a fan of simple, clean and minimalistic theme.
This is a MiRound default lock screen.
Unlock it with simple swype up action.
If you prefer different lock screen, you can bring different lock screen from different theme.
MIUI also lets you do mix & match.
4x1 Global Search (comes with the ROM)
4x4 Jorte Calendar with weather calendar add
I had to change rows from 4 to 5 @ Launcher Setting menu.
MIUI doesn't have separated App Drawer, this is the 3rd home screen.
Although you can simulate it with AppDrawer app.
