Feature request: (work)Spaces feature of Mission Control

[tblancher]

skippy-xd is pretty nice, but the real killer feature of Mission Control that appears to be missing is drag and drop placement of workspaces, windows on workspaces, and creation/deletion of workspaces. I use XMonad with Xfce4, so getting that working for me is a long shot. As it is, I don't have a need for skippy-xd now, but if I could get the workspace features working, that would be awesome.
