I am new for Linux and Ubuntu. I didn't like unity's built in application switcher.

I have been looking for simple and fast (like in windows 7) application switcher for Ubuntu with unity desktop. Which shows a grid with opened applications and one can switch by using up/down/left/right arrows or by subsequent pressing alt+tab

I have tried all options in compiz and the most close option was static application switcher but I cannot use arrows to switch between windows.

Do you have any suggestion which complies to my needs?
I would appreciate any help.
