Allow adding custom details
I’d like to suggest to add the following feature: ability to custom details to a contacts.
The user could a new field, choose its name and value. Once they create it, when creating/editing another contact, this detail could be re-used: (1) it should be in the ‘New Detail’ list; (2) even if the user adds a new custom detail with the same name, it should be linked together (in the sense as it is the same column header in a table).
