That's perfectly serviceable. Depending on the context, sending a custom message could be simpler because it avoids duplicating the logic of inserting the new tiddler title in the list. It also handles the history processing correctly. You'll only be able to use the custom message approach if you're executing in the context of widget in the DOM.
