[SyncEvolution] Syncevolution supports preserving unique fields yet? (sort of related to my last note - call it part 2)

After reading the wiki page titled: Data Conversion and testing (http://syncevolution.org/development/data-conversion-testing) which was last updated November 2009, I have one more question. Question: The page mentions that syncevolution will soon be able to preserve fields that are unique to evolution and not other platforms (and presumably the other way around too). How soon? Or has that been done for 1.0 beta3 Thank you again! --Jeff
