A nice new feature of the upcoming iOS 6 firmware (coming this fall) is when updating apps from the App Store, the App Store app doesn’t close on you when you tap update or update all. Before, it would close after every time you tapped update or install causing you to have to reopen the App Store for each app. The app icon gives you a progress bar and the install button says installing. This helps me a ton because I like to update apps individually so I can read their list of recent changes and I can skip ones that I want to remember to review. You also do not have to enter your password for updating apps.
