The Navigation Breadcrumbs plugin for Movable Type 4 (MT4) adds navigation "breadcrumbs" to administration interface. These are links at the top of each screen that helps show you where you are in the interface, and provides links to go up one or more levels. Previous versions of Movable Type includes these handy links, but MT4 does not. So if you like those navigation links, use this plugin.
