While doing my daily rounds of email checking I had noticed a new icon in the top of my Google navigation bar. The new icon, a square with a plus in it, can be clicked to open a pop-up that will allow you to quickly post or share something onto Google+.
You have the same full capability as you would on the full Google+ site – allowing you to share photos, links, events, and polls. The new icon appears across all Google services such as Gmail, Drive, Photos, Maps, and even the Google Chrome start page.
