With Lion it seems the mission control is separate for each screen, however I have not found a way to show a different desktop/space on each screen.
Basically I want it so that when a do a swipe on my track pad to change space, it only changes scrolls the spaces on the monitor which the cursor is in.
I have tried to set a fullscreen app on my second monitor but it always comes back to my laptop screen. Yet Apple seems to think this is possible judging by the second image in the scroller on this page (http://www.apple.com/displays/) (This image also shows a menu bar on the laptop and 2nd display, how is that done?)
So how can I individually set spaces per monitor?
(also in the old spaces you could drag windows between monitors as well as spaces, is this not possible in Mission Control?)

This is an excerpt of Appple's Application Kit Release Note for Lion regarding fills screen apps & multiple desktops.
Multiple Monitors and Full Screen (New since early 2011 seed)
We have made some simplifying assumptions for Lion Full Screen behavior on multiple monitors. Multiple monitors are treated as a single unit by Spaces, and therefore are also treated as a single unit in Full Screen. This means that all monitors will be dedicated to windows belonging to the full screen application, and there can be only one primary full screen window visible at a time. A secondary monitor is useful for inspector windows.
Secondly, because the menu bar is located on the main monitor, the primary full screen window will be located on the main monitor as well. This allows the menu bar, floating toolbar, and full screen window to maintain their interrelationship on the same monitor.
