From the readme: This plugin enables TiddlyWiki to embed a modified copy of itself (an "innerwiki"). The primary motivation is to be able to produce screenshot illustrations that are automatically up-to-date with the appearance of TiddlyWiki as it changes over time, or to produce the same screenshot in different languages
