Dennis,

           This add-on is still under active development and maintenance.  If you are sufficiently Python-proficient to make these sorts of changes, I would strongly encourage you to make contact with the current maintainers of the add-on and discuss joining them in the effort.

            The page Rui cited gives the email address of the primary (perhaps sole) developer:  André-Abush CLAUSE <dev@...>

Always remember others may hate you but those who hate you don't win unless you hate them.  And then you destroy yourself.
