Unity: The Systray Is Back, Themable Top Panel, Hide Animations, More Ubuntu 11.04 Updates
A new Unity version was released a few minutes ago with some exiting new features. New for Ubuntu 11.04 I mean, because they are something that's always been around in Gnome but not available or removed in Ubuntu 11.04 / Unity. The biggest change is the addition of a systray (notification area) to the Unity top panel. But it's different!
