All I used for this is Apex Launcher, my own made wallpaper, and cold fusion icons.
Apex launcher: http://goo.gl/Lilqt
Cold Fusion icons: http://goo.gl/vO8tI
Apex launcher settings:
-Portrait grid: 7 x 5 (Same with landscape)
- Uncheck ‘Show desktop indicator”
- Never show persistent search bar
- Hide notification bar, shadows, and icons labels.
You can do whatever in the drawer settings.
-Scroll all the way down, and check “hide dock”
Now you can do whatever you want with all other settings.
I put some gesture like swipe down for notification bar, and more.
I also put some invisible icons like: app drawer, settings, battery info, and etc.
