MIUI MiHome launcher is my new launcher home.
It is fast and lightweight as the Zeam Launcher, but the best thing about MiHome is that your home screens are your app drawer itself. You can customize it by grouping the icons by folders. You can also add widgets to it. And most of all you can apply themes. Amazing!
This launcher is available for android 2.3 and 4.0.
I hope you can try this launcher.
