adress book import
when using the adress book functions of adium you have to edit all your adressbook contacts.
for example your buddy "john average" uses icq, you have to put "111111111@icq.your-jabber-server.com" into his adressbook card and change the service from icq to jabber. otherwise it wont work with adium. it would be very very handy if adium would just know that it is a icq contact, check the gateway, see "aha - this user is registered via gateway blah" and everything is fine.
adium could even show the correct service icon etc. pp.
probably this point needs some discussion as it probably needs a lot of hacking. but from a user perspective this "it just works" integration would be really convenient and cool :-)
