Cross-references are a complex feature that will come later. We intend that the paragraph list formatting be usable for automatic figure numbering. Essentially, if you make a numbered list, give it a name like "Figure" and tick the Global option, set Restart numbering to Manual Only, and set the text to something like "Figure \#", then it will insert a number at the front of the paragraph that increments automatically as other figures are added before it in the document.
