In Lion, being able to swipe between desktops with the trackpad is great. However since adding another monitor to my setup, what I really want to be able to do is swipe desktops across monitors. E.g. if I have the following setup:
Desktop 1 | Desktop 2 | XCode | Chrome
Instead of swiping left from Desktop 1 replacing the contents of both screens, Desktop 1 is displayed on the left hand monitor and Desktop 2 on the right. Swiping left moves Desktop 2 to the left hand monitor, and full screen Xcode to the right hand monitor. This would be especially useful as XCode/Chrome etc. just blank out the second monitor when in fullscreen mode, which is really annoying!
Is there an app or setting that can achieve this?
