The appearance and contents shown for a list of name can be changed by tapping the Settings button (Cog) on the bottom left of the screen.
The list names are displayed with a background image. This image can be removed completely, or made more transparent.
The List can be displayed with just the Name shown. However, it is also possible to also display address, extra info, company, phone numbers, email addresses and birthday.
Obviously to show these extra items, they will have to have been typed in previously, or be present in the Contact information if the person was imported from Contacts.
Examples are shown below.
