Can we be honest with ourselves for a bit? Notifications on Google+ have sucked for a while. It's never clear what's new and what's old, they're cluttered with information, and up until recently, they've been tucked away in the app underneath the sidebar navigation. Well at least one of those problems is getting fixed today as the Android app gets an update that creates a special new section for notifications on the right-hand side of the app. Also, you can access it in more places! Not everywhere, but a lot more!
