Rated 5 out of 5 stars

The extension is very useful and comfortable, but I think it misses some feature:
- I'd like to choose "contacts from all Address Books" in the Address Book field (instead single address books only). It would be a very useful feature for me.
- I'd like to put it beside folder's sidebar instead than under it (with wide screens I've much more horizontal space, and I use many folder so the folder's sidebar is very hight).
