Abstract: A method and system for coordinating software extensions by utilizing a central management system. One or more extensions register with the central manager, the extensions being capable of providing extended functionality to one or more lower level functions. As calls are made from an application program to a lower level function, the calls are intercepted at the central manager. Each of the appropriately registered extensions is then notified of the existence of the call, thereby allowing the extensions to provide extended functionality thereto.The call is then passed by the manager to the lower level function, which returns a result of the call to the manager. The extensions are then notified of the result of the call. This enables the registered extensions to modify the result of the call to provide its extended functionality.
