Only if you'd want to do formatting with extreme flexibility/customizability.
IMHO, the way MSPro currently handles formatting ChordPro files is sufficient for the purposes MSPro is intended for. MSPro is not a typesetter, it should format the songs for maximum readability on a tablet screen. Yes, it would be nice to have some additional settings for tab size and such but I don't think much more would be needed. Of course, users will ask for more, that's human .
Just like nicely formatted PDF scores, with heading and footers and so on. With MSPro, you apply cropping to get rid of the frills and obtain maximum readability.
