Superfish is great. The mouseout delay makes drop down menus more usable. But submenus should disappear immediately when you rollover ANY sibling. Currently, submenus only "disappear" when you rollover a sibling WITH children (because the submenus have to change). If you rollover an EMPTY sibling (one without a submenu), any previously revealed submenu should ignore the delay and disappear immediately. Stated another way, the delay should be 0 when the user mouses over a sibling without children. It's confusing (for example) when you rollover "Home" in a navigation bar and the subnav for "About Us" is still showing.
