I think there's a bit of confusion here. Here's how I think about this stuff: * Any tiddler whose title starts $:/ is a system tiddler. (Independently of whether it's a shadow, a plugin or anything else) * There are special tiddlers called plugins that each contain a bunch of shadow tiddlers. These shadow tiddlers have the property that they can be overridden with a real tiddler. A consequence is that if one deletes a tiddler that is overriding a shadow tiddler, then the shadow is reinstated * There is a special plugin called $:/core that contains the TiddlyWiki core code and user interface * An "empty" TiddlyWiki must still include the $:/core plugin in order to operate correctly I think that covers the concepts you're trying to describe. Note that there is no concept of "default shadow tiddlers". Best wishes Jeremy.
