I just switched from 10.04 to 12.04. I am using Gnome Classic. In 10.04, right clicking an icon on the menu bar (I think that's what it's called - the bar with Applications, Places, and quick launch icons) would give the option to remove it. However, in 12.04 right clicking only gives 'Launch' and 'Properties' options, and Properties does not contain an option to remove it. How can I remove an icon?
