Tried the demo of the address book, but it looks really oldschool to me, and also has the annoying pages. It's all about realtime searching now.
I like the addressbook as it is now, except the way it searches.
* It doesn't take parts of the name. so looking for "daniel" by typing "dan" won't work, probably because it would come back with too many options because it's also looking in all other modules.
* It would be nice to filter realtime (using a new search box), hidding all contacts that have nothing to do with the query.
