Google have donned their magic fingers and made some changes to some of the most-requested features for their Gmail for iOS app. They've announced the changes today, which come in three new features.

First up we have full Notification Center support, the ability to send messages from your alternate e-mail addresses, and an improved login experience. Now Gmail is fully integrated with Notification Center and even supports banners, alerts and lock screen options. Plus, notifications are now 'incredibly fast', up to 5x faster than the previous version of the app.

The second update to the Gmail for iOS app is the ability to send e-mails from your alternate e-mail addresses. If you have this configured through alternate sender addresses in Gmail on your desktop under Settings -> Accounts -> Send mail as, you will see a From: option when composing new messages with the new app.
The last change is the login process which allows you to stay logged into the app for as long as you'd like. You can still log out of your account, but with the new app you won't be logged out of the app after a certain period of time. Google have promised to continuously update the app, and they are looking forward to bringing you new features in the future, including support for multiple accounts.
