In the early morning (here in the U.S.), François Beaufort treated Google+ to a look at rich notifications on Chrome OS. However, it was an icon pinned to the launcher tray that really caught everyone’s attention.
If you take a close look, the icon resembles four messaging icons stacked upon one another. This heavily hints at the possibility of Google rolling out a unified messaging service. François Beaufort was quick to state that he does not yet know what that app is, however, he adds a sly little wink at the end to keep us wondering.
