Here are the current limitations of the add-on:
- Make sure images are inserted as Drawings. This is to make sure the add-on correctly copies the image during the merge process.

- The add-on reverts bullets into the default format.
- Charts inserted in table cells are not copied over during the merge process. This is a limitation of AppScript as well.

- Special text formatting (highlight, italicized, bold, etc) is not read by the add-on for texts inside numbered lists. As a workaround, manually type in numbered lists and use the indent sliders to indent blocks of text.
