I'm dissatisfied with the Contact feature's default display order, which shows given names before family names. In my cultural context, the standard notation is to write family names followed by given names, so the current requirement to place names after family names makes the interface extremely unusable.
Please allow users to choose between both the "given name-surname" and "surname-given name" formats.
As a Japanese person, I suspect this would be equally true for Chinese and Korean users as well.
