|Q:||I use the address book extensively to maintain addresses,
phone #'s etc.
It would be handy - for me, at least - if the address book would display in the message edit/preview pane when an address receives the focus (rather than having to open Properties).
To make it more complex it would probably need to be a toggle - since some folks probably only keep email addresses in their address book.
I know this isn't trivial - but it would be a nice feature for those of us who keep all our contacts in the address book.
