My notebook has a widescreen display so vertical space is an absolute premium for me. When I installed Ubuntu 11.10 I was disappointed to see that a new icon confusingly named "Dash Home" had been added to the very top of the Unity launcher. I can't move it to the bottom (by dragging it) and it doesn't have a context menu with which to remove it (by unchecking "Keep In Launcher"). It's horrible.
How can I remove it from the Unity launcher and reclaim the space that was taken from me? (I realize that if it's removed I'll have to open the dashboard with the super key – I'm fine with that)
