HTC, you ever use the "notepad" application in MacOS? Near the bottom right of the notepad, the page is "dog-eared" showing you a small piece of the pages below. If you click the dogear, it cycles to the next page.
Something like that might be more useful than a pull down menu when you are trying to switch maps in flight... just click the corner or a button to instantly change to the next page instead of pull down a small menu.
Other than that I love the custom pr0n--I mean map feature.
