It's just same with Windows 7 Task Bar! (see the promotion video)
You can multitasking and task-kill everywhere, anytime.
Tab the start button to show/hide the task bar and Long press it to show/hide the start menu.
* In some versions of MIUI, you are supposed to check 'Show popup window' in application setting.
