I'd like better visibility into how the merging works. Which entry wins? What order is used for phone, email, addresses if different? Which photo wins? AND.... ability to UNDO a merge. I accidentally merged 1 contact because of similar first name with no way to undo it. I had to recreate contact #2, and manually remove the merged info from contact #1.

I want the option to click on two or more names in the full contact list to merge them. If a name comes in wonky, only I will know it's a duplicate.

But I have multiple Allisons in my address book it thinks I should merge, but they are all different people. So that merge all button is super scary to me right now. Only first names should not recommend a merge

I would also like to see this happen, especially when it comes to email: JSmith@gmail.com and John Smith as a contact should populate the option to confirm they are in fact a duplicate and the same contact

Also, I'd vote that "Smith, John" and "John Smith" should match.

Some contacts had first and last name matching but because there was a middle name on one of them they did not match as duplicates. I’d rather have too many duplicate matches and tell the system it’s not a match, than not know if there is a duplicate.
