Hi all, I'm a fairly new Mac user; on my Snow Leopard installation swiping four fingers sideways reveals all open applications in a row across the centre of the screen (also accessible via the command + Tab shortcut) which I found to be a useful gesture. However in Lion, I find that swiping four fingers left or right does the same action as swiping three fingers (i.e. switching between virtual desktops and full screen apps in either direction) which is redundant. Is there any way to get the Snow Leopard functionality for this gesture in Lion? I couldn't find anything in the Trackpad preferences.
