Has anyone else tried to use multiple monitors with Lion? When you fullscreen apps it totally wastes the space on the other app, and my usage model for Spaces no longer works either (rows rather than columns). It works really well on my Macbook Pro's monitor alone but it really seems built for a single-screen environment. Spaces no longer works, exposé (multi-apps) no longer works, both buttons just activate mission control which is a conglomeration that does not do any one thing better than exposé and spaces did alone. Dragging an application window between spaces is possible but in order to drag it back you have to go into that space then re-activate mission control then drag the window back. It's so, so unintuitive.
