Ginhead:However, I am a little afraid that the "Key" field will be eliminated
Don't be. Its name will change (to "Sort as" or something similar), but the effect will be the same.
Ginhead:it would be nice to be able to add extra fields and name them as we want for contacts.
Already on the list - although it may not make it into the first cut. But don't be perturbed by that - the file format is inherently extendable, so it will be possible to add this (or any other feature) in future without needing any conversion of any kind - existing data can be extended indefinitely in place.
Ginhead:It would also be nice if we could choose how many of these fields we want, i.e. the ability to discard all of them except the "Name", "Key" and "Email" fields
You'll be able to add and delete your own fields, but you won't be able to modify the layout of the contact editor to delete standard fields. It *may* be possible for developers to do this via extensions, but I haven't decided that yet.
Ginhead:In your reply you did not say anything about (1) and (2), does this mean that it is not possible or (on the contrary) that it is so evident that it will be part of the next version ?
?? I said that points 1 to 4 were all already covered.
Cheers!
