Adds Arabic, Roman or alphabetical numbering to your titles, with the separator and final characters of your choice. The numbering takes the form of characters inserted in front of the headings, and can be changed by hand or erased. Exchanging two headings is not a problem. To update the document numbering, the application remembers the previous numbers inserted and removes them before inserting a new one. The settings are saved in the document and you can save default settings for your user. The entire extension is controlled from a side panel and a faster button for updating the document.
