Answering my own question, you can't include widgets. But I just realized that when you transclude an AsciiDoctor or Markdown tiddler, the text gets rendered appropriately. So there's better authoring possibilities there than I had previously thought. You could use a regular tiddler to present mutliple AD or MD tiddlers.
Small note: There's no tag tip on the AsciiDoctor icon out in the sidebar. Thanks! -- Mark -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
