What I do miss in Natty (Alpha 3 + daily builds) is the possibility to click on the app. icon on the Unity launcher bar to minimize the app., not only to launch/restore it. This is standard behaviour on other desktops (at least on KDE, XFCE & MS Windows - don't know for Mac), and I think this should be implemented as well on Natty/Unity.
