It’s now easier than ever to manage standard extra values. A new editing window allows you to rename, sort extra values in their current location, or move them to a new location.
The StandardExtraValues2 file (in Special Content > Text Content) still determines the naming and placement of standard extra values for People, Family, and Organization, but the new editing window offers a user-friendly way to manage People standard extra values.
To use it, simply go to one of the locations with standard extra values -- the Extra Values tab, Member tab, or Entry tab -- and click the Edit button.
