There is indeed no guarantee of "referential integrity" as you say, and that is exactly the point of FN. I want to store that my contact name is John Doe, but I do want it to display as “My very best friend” in my contact list.

If you take a close look at the patch, you will see that it does not remove the globalContactStoreFN option. So : * if I want FN different from N, I set both, * if I want only FN, N will be empty (and thus it will not work on Apple clients as you say)

* if I want only N, FN will be set following globalContactStoreFN option.

I believe it's the way a lot of software work, and I may be wrong, but I can't see how it breaks the way it works now: just don't set DisplayName in the interface and the behavior doesn't change.

I would very much like to see the best of both worlds.

Cheers, and many thanks for your very detailed answer. -- Jean-Philippe Garcia Ballester Le Wednesday, March 23, 2016 10:29:44 PM CET Ján Máté a écrit : > Hi Jean-Philippe, > > > thanks for your patch, but unfortunately I cannot add it to the official release :-/ > > This feature was discussed multiple times, and there are reasons why we don't want it: > > 1.)

It is much better approach than using unstructured data; personally I used it multiple times to fix common errors in our database (which currently contains 18807 contacts). > > > Cheers, > > > JM > > >> On 23 Mar 2016, at 19:42, Jean-Philippe Garcia Ballester <jean-philippe(a)demo-tic.org> wrote: >> >> Hello all, >> >> The “Formatted Name” field of contacts is not used.
