Android: One of the most useful features of Android's notifications is the ability to perform actions like archiving an email or "favoriting" a tweet from the notification. Now, Pushbullet can take those same actions with its mirrored notifications.
Previously with Pusjbullet, you could see your Android notifications on your desktop. However, the quick actions that accompany the expanded notifications were absent. Now, you can use those too.
You may not get a lot of new functionality (we imagine you can already archive an email from a desktop), but if you're already mirroring notifications, this makes it a whole lot more useful.
