On the newer miui builds, the notification bar is divided into two pull down zones: the left opens notifications and the right opens controls. Though I like the division or tabs of the notification menu, using a larger screen phone such as the evo or hd2, I have found it difficult (requires more of a stretch) to pull down from the top left as I am right handed. My suggestion is for a "smart" notification bar that by default opens up the controls. However, whenever a notification is received, for example: a email or text message, the notification bar will always go to the notification page. So, whenever I have a notification, it will automatically pull down to the notifications, if not, the controls.
