Customize views for type-ahead

When using the type-ahead function, contacts that don’t have an e-mail address in their contact document are shown. Is there a possibility to extract those? Is their a view that i can modifiy, or is this not a good idea?

When using the link under “to” the all contacts in the directory are listed the contacts without e-mail as well. Could this be modified?

Is it possible to show the e-mailadrress of the recipient when using the type-ahead in the address bar?

thanks for you help
