New address widget in 2.3.0

["Bobby D. Bryant" <bdbryant mail utexas edu>]

I upgraded to 2.3.0 on Gentoo (by hacking the 2.2.6 ebuild) in order to  
have a look at the new address completion widget, but I don't see  
anything different than before. (I.e., the expansion of nicknames is  
done by means of a drop-down menu, and you have to reach for the mouse  
to actually pick one.)

I checked the "About" menu item to make sure I'm actually running  
2.3.0, and I am.  What am I missing?

Thanks,
