One of the new features of elementary OS Freya is a new notification system. It now looks more beautiful and it’s also smarter than the one in Luna. The new notification system not only shows IM messages, audio track changes, etc, but it also shows completed Terminal tasks, what I find very useful.
Elementary OS is not famous about it’s customization, so I was surprised to see that the new notification system also gets an own Notifications settings menu within Switchboard. It’s going to look like this (click on the image to enlarge):
