Android Police have some great news for Gmail for Android fans, where in Android 4.2 you'll have pinch-to-zoom abilities in the Gmail app. Also included with Android 4.2 is a new swipe to delete/archive, as shown in the video below.
The video above was done on a Galaxy Nexus running Android 4.2, meaning that the new abilities aren't limited to just Android 4.2 which is great. Android Police have noticed that the 'About' screen notes it's Gmail version 4.2.
Swipe to archive/delete is as simple as swiping a notification away, where you can swipe an e-mail out of your inbox, or archive it somewhere. Google give you some nice options, where you can change your swipes to "No effect", "Archive or delete" or "Always Delete". The default option is set to "Archive or delete" which will send swiped messages into archiving when you're in the inbox, delete swiped messages when you'er in All Mail or Sent, and remove a label when you're in label-only view.
The last feature the Mountain View-based company have added into Gmail is the ability to report a message as phishing - nice.
