There are times when we require a little more information than shown in All contacts. For example you may require an emergency contact. It is quick and simple to access these details by going to Contacts > All Contacts
Type in the name of the contact in the search bar
You will see there is limited information here however, by clicking on on the coloured box with the intitials in it this will take to you to their profile where any information they have put in will be displayed in the Custom Fields.
