Comment 6 for bug 667245

This third mockup represents what you see when you navigate to the second workspace and open a window: a third empty mockup (represented in the sidebar by a third purple space) appears.

In the mockup, I navigated to the second workspace and opened a GIMP window. I might as well have opened it in the first workspace and dragged the launcher to the second purple space. If I then close the GIMP window, we would revert to the second screenshot: the third, empty workspace would disappear.

The advantages of this approach are:

- You can easily move windows between workspaces by dragging their launchers up or down.

- You can easily (and visually) keep windows thematically grouped by workspace, e.g. office apps on the first workspace, media apps on the second workspace.

- You can easily switch to a workspace by clicking it, since they show an empty space above the launchers.

- You can easily open expose for a single workspace if you click again in that empty space.

- You can easily reorder workspaces by dragging them up or down in the sidebar.

- You can easily open an app in a certain workspace by dragging it from the dash to a particular empty space.

- You can easily set in which workspace you want "favourite" apps to open by dragging their "pinned" launcher to a purple space.

- It allows you to visually separate apps on the active workspace from apps on other workspaces, thus saving you time to find e.g. a particular app you want to restore.
