In Four changes to Gmail contacts Gmail’s Benjamin Grol (Product Manager, Google Contact) notes four new enhancements to Gmail’s contacts, see below:

1. Contact merge (and an important caveat about auto-complete)
I’m sure this will be cool for people who use Contacts more than I do.

2. All Contacts
YES! YES! YES! I LOVE this new button and I was just using it tonight with my wife while searching for a contact “I knew” was in her contacts list (actually I was wrong).

3. Remove people from My Contacts
This will certainly be handy for some.

4. Search across all contact fields
YES! YES! YES! Great, I also used this to verify that I was wrong (see item # 2 above). Just like the All Contacts this is one of those things that after its added you just find yourself thinking this should have always been a feature.

All I can say to the Gmail team is to keep up the good work, and for people to keep suggesting things for the improvement of Gmail.
