Ghost for Google+
Mac OS Social Networking
Ghost for Google+ discreetly sits on top of your desktop wallpaper, providing you with instant access to your Google+ account without the need of using your web browser.
Hover your mouse over the app's window when it is active and the semi-translucent Google+ page will become fully visible, bringing the Ghost to life!
Ghost for Google+ is perfect for staying on top of all your social networking needs (your Profile, Photos, Circles, Chat, etc) and you can even tweak the app's window height, width, placement and opacity.
