Contact setting to include which e-mail address to use for e-mail to that address
I frequently forget to use the same e-mail address when sending an e-mail. It would be useful to be able to select a default address for each contact address. It could be initially set using the first address.
Also, I like the use of the aliases (email@example.com) to help sort incoming e-mail. If the default address could include the alias, if any, that would be a plus.
