The Gmail app for Android has been updated today to include a set of features that should make responding, organizing, and searching much quicker. Through Android 4.1+ notifications, Gmail will allow you to quickly Archive (delete too) or Reply to messages without having to enter the app. Funny thing is, I was complaining about the lack of a method to delete emails from the notification bar this weekend. Google, reading my mind.
Also, you’ll find better search suggestions and faster overall search to help you find things both offline and online.
Sadly, this does not introduce a new UI to bring it up to snuff with the iOS version of Gmail.
