Notifications from Chrome may soon behave like all of your other OS X pings.
Google Chrome already has its own desktop notificationsfor Windows and Mac to alert you to new Gmail messages and other updates. However, those pop-upson Apple machines act independently from all of the other OS X notifications, so you can't employ that handy Do Not Disturb option to keep them hidden or peruse 'em from the Notification Center.
The good news is it looks like Google's browser will soon offer the native push notifications on Mac as the feature is currently in testing. If you're feeling adventurous, you can give it a go by enabling the feature via this linkin Chrome. Be warned that the tool isn't without bugs just yet and what appears in the stable version browser differs from the unstable nightly builds pushed to Chrome Canary.
