The updated App also sticks your most important message actions to the top of the screen while scrolling through a conversation. You can also tap “Show Quoted Text” to view previous message content.
Most importantly, the update adds support for Google’s highly famous “Priority Inbox” feature. If you have activated Priority Inbox on your Gmail account, your priority inbox mails would get an “Important” label and you can also add a shortcut to “Important” to your home screen.
The update is only available for Android 2.2 (Froyo) and can be downloaded via the Android Market.
