Looks like we didn't have to wait too long after all for that fancy new Gmail app for Android. The new app -- Version 4.5 for you folks playing at home -- kills the action bar at the bottom and moves things up top, and introduces the left-anchored drawer for things like accounts and labels. You've also got the much-desired pull-to-refresh, and conversations how have a new look as well.
Spend a couple minutes with the app and it you'll be quick to find that it's worthy update, though you will be stretching for the top of your phone when you're working with individual e-mails, instead of easily reaching the archive and delete buttons at the bottom. We'll have to see how much of an annoyance that is over time.
The update's propagating now, so head on into your local Google Play Store to snag it.
Thanks to everyone who sent this in!
