Currently I use it on two monitors, both have independent 1-9 workspaces and you can move your windows across them with shortcuts or by dragging. On my big monitor I mostly just use the first workspace.
When you plug the monitor out it collapses the workspaces and tries to fit them on empty ones on the Mac screen. It remembers the previous setup to restore them once you plug the monitor in again.
