If you need to extend the behviour of a plugin, or override it you need to do it in the following way:
mw.PluginManager.add('myExtendedModule', mw.PluginManager.getClass("otherModule").extend({
//you can override any method of the otherModule you are extending in here
//or add your own logic, like event listeners and call the otherModule methods directly
}));You need to remember not to include the otherModule in the available modules in your player and set only the myExtendedModule as enabled, otherwise both plugins will be initiated in your player, and it will probably yield unwanted results.
