Kent Sutherland has released Warp 1.1 which adds the ability to see a small preview of the Leopard Space the mouse is moving towards. In addition, the new version will no longer activate while a screen saver is running. German and Japanese localizations have been added.
With Leopardis spaces, one can move to a new Space in several ways. Moving the mouse is not one of them. With Warp, a preference pane, the user can slide the mouse to the edge of a screen, see a preview of the Space, then select the Space to move into.
Warp 1.1 requires Mac OS X 10.5/Leopard and is free.
