One of Pushbullet's coolest tricks is the SMS reply functionality accessible on your computer. Just hit the reply button on your PC or Mac when a synced notification pops up, and you can type a reply. There's a new update today that extends this feature to the top messaging apps on Android, but there are a few small caveats.
Messaging replies in Pushbullet will work for WhatsApp, Telegram, Hangouts, Facebook Messenger, and Line. The team plans to add more services soon, so don't fret if your preferred platform isn't supported yet. To get this feature working, you will need to be on Android 4.4 or higher, and Hangouts replies require the Android Wear app the be installed. You don't have to actually have a Wear watch or even open the app. Yes, it's weird.
In addition to the expanded messaging replies, you now have a handy little widget that can be used to toggle the Android-PC notification sync on and off. The actual toggle is way down in the Pushbullet settings, so that's a thoughtful bonus. You'll also get heads-up notifications for some pushes on Lollipop devices. The update is rolling out now and should be available for download soon.
