Grouping all your windows in one space!
I know I said I wasn't going to be making Leopard tips just yet, but this one was just too good to pass. You probably saw in the Apple video preview of Leopard how you can easily change from one space to another and how you can quickly move windows between spaces. There is something really cool that wasn't mentionned though. You can group back all your open windows in the main space. To do this, when you are in the Spaces environment (by clicking F8), hit "C". All the open windows will group in the main space. You can ungroup them by hitting "C" again.
