There is a new, currently free, app in the Mac App Store for Apple users in the Google+ fold. It’s called Tab for Google+, and places an icon in your OS X menu bar. Clicking it displays your Google+ stream by default, but there is a lot more to this drop-down than a simple feed.
Created by the same people that produced FaceTab Pro, Tab for Google+ offers notifications, circle and profile access, photo viewing, and more. You can check in and post right from the drop-down menu. Theming is currently limited to a single sky hue, but the layout is nice, despite blurring in the menu icon.
FaceTab Pro is $1.99, so that’s a possible indication of the future price point for this OS X application.
