Was searching for SO long for this, the headers in Thunderbird take SO MUCH space!!May i suggest and extra option? There's already the option for showing only adresses... but maybe it could show only Names?? It could be SO great :)
It works under Thunderbird 6 !!

This review is for a previous version of the add-on (1.4.0).

This can be switched on in the preferences:
Tools->Options->Advanced->Reading&Display->Show only display name for people in my address book
