Me too:

Requirement:
Enhance desktop management in order to make virtual desktops easier to use.

Possible Interface:
A floating desktop selector that can be hidden or pinned.
The desktop selector displays a thumbnail image plus a user-supplied name for each desktop.
Each desktop can be associated with a user defined function key.
The order of the desktops can be changed by dragging and dropping within the selector.

I'm not yet clear if Groupy would meet part of this requirement - perhaps it needs to allow the user to group fences.

Many thanks
