The favorites list is actually stored in a text file, so an export feature implicitly exists
, but there are no meta-data stored with it. However, that's what the user-data DB is for... besides "ranks" (which is meta-data) there's also "comments". The comments are not yet supported GUI-wise, though, they have been added to the DB schema "for future use" when I implemented the ranking feature.
That said, there are serious plans to redo the "favorites list" completely anyway, and numerous related feature requests reached me over time... so I'll also consider an explicit export feature now
