Italics:
Probably. I've never looked in to -- but then again I am not at the point where I am outputting fancy reports. Or any reports, other than Gedcoms to go to other places (GedMatch, FTDNA, etc.). For me that is a non-issue (and I say that even though I am a degreed Librarian and use bibliographic formats a lot).
As always, I give my personal opinions just so others are aware of them, as alternatives. To each their own way.
