Show contact name in folder view

Apologies if this has already been submitted, my cursory search didn't seem to find much!

What I'd like is for when you receive an e-mail from a friend whose e-mail matches one of your contacts, to display the 'contact' name rather than the name that the person themselves defined in their e-mail client.

Also either an icon next to their name or ability to display them in a custom colour/format would be great!
