[Evolution-hackers] Header autocompletion hack

[<evolution adaptivetime com>]

im try to alter the little autocompletion dropdown of people to add an icon appended to the far right as well as alter the address line.  is the dropdown a custom widget?  what file(s) is this in?  i also want to edit the addressbook with the addition of the icon to the end of each address.  ive been sifting through the code with no success.  help me please. :(
