Hey, almost a month since last post :-/ This feature is really great if you want to create different blocks from one view. I had to create a view that contained recent posts, popular posts and popular posts today. To manage this you have to create 3 different page displays and the displays need different sort criteria and filters. At first I thought this was easy, but when I started to modify page display #2 page display #1 got modified, jeezez. Then, after 48 minutes of drupalfrustration I hit the help menu. The solution; A button called override. If you need unique displayes hit this button on the filters and sort options that you need in you're blocks og pages.
