haven't tried this (enhanced address book) as yet, but i did just download and install. It appears to be free, but sometimes "betas" can turn out to be bait...
http://www.cobookapp.com/ I like it a lot at first glance, but...
First negative is that it doesn't replace the quirky, unintuitive, buggy (in Snow Leopard, anyhow) Address Book pane that appears when you click the "Address" icon in a new e-mail.
Edits:
Oops! I just discovered that it's got an "Email All" command under the work wheel.
In syncing with Address Book, it doesn't pick up my "Custom" phone # labels.
It didn't pick up my preferred e-mail address pref for my daughter, but I managed to reorder her addresses...once...can't figure out how to do it a second time. (Got it... I had to quit and relaunch.)
Time to contact the developer.
Looks like a promising app (particularly since Lion's Address Book seems prone to negative press; I wonder what it'll cost? (If it's reasonable, I'll spring.)
