Would it be possible to...

["Mark A. Flacy" <mflacy verizon net>]

...have the Balsa method of entering the various e-mail address more  
like KMail's?

In the screen shot, the "To" button is a picklist of "To", "CC", or  
"BCC".  When you add a name, you get an additional row.  If you want to  
delete a name, you click the button to the right of the name.

It's really nice to use if you ever have to edit the addresses in a  
reply or new e-mail.
