mmm i'm not sure if you understand very well, sorry for my low level in english on that...
in the contact list, you can choose to change the name of a contact to everything you want and it will always show that, not the mega-long name that your contact really have...
it would be great if we can do the same thing with the display picture of a contact...show his photo or a drawing that represent him better than his actual display picture...
am i more clear?
