Comment 11 for bug 868423

Just to be clear, the workspace switcher icon is not like any other application, it's a special icon. So some code is needed in 2D and 3D to make is appearing/removing depending on the number of ws (or for triggering or not the expose effect if we keep it always).

Adding a quickist to it to launch an external application to define the number of workspace is definitively doable. I just want to emphase it's not lightweight and need testing. If this is a real priority, we can see if the FFe/UIFe (as it won't be out before thursday) will get acked and try to get to it.

It will surely drop other work items/features/bug fixes on the cycle though.
