Today for Android users, Gmail is getting a minor boost in its user interface. Starting with the conversations view, threads that have multiple messages back and forth will be better paired with a card-style UI, allowing for an easier time viewing messages. In addition, when you select multiple messages for archiving or deleting, a large “check” will appear, making sure you know exactly which messages you are working with.
To top it all off, there is also an “account sync” notification inside the app, just so you can be sure to never miss another important email.
You can expect to see the update live in Google Play sometime this week.
