Christians have often made special decorated editions of the Bible, so we would have no objection to a red letter edition of our translation if there is a demand for it. Also if someone wants to volunteer to start converting the text into a version with metric measurements for readers outside the United States, that would be a good idea too. We assume there will be some who will want audio versions of our translation. There may be many other ideas for special versions.
But all of these are publication and formatting questions for the future. Right now our job is completing a translation that people will want to use in multiple formats. If some formats are not feasible as print editions, they may be electronic editions.
