Feature Request: Captions
It might be nice to add captions to the image insert and table insert feature. This way you could refer back to the table or image in the body of your text as "Figure X" or "Table X". It could auto-increment like the footnotes and endnotes do. Perhaps they could be hyperlinked to the image or table with an anchor tag so that readers could click on the reference and be taking directly to it.
