Can't type email address in the To/Cc/Bcc  in quick compose Email

It seems that in the out-of-the-box email quick compose in v7 you can't just type in an email address in the To line, it must be a contact/account/user and it must be typed by name to select the person to write to. Same for Cc and Bcc.

This is totally counter-intuitive as most of the time we are used to using email address in the To line.

Not only that, but when working a case the "+" on the Emails subpanel has the same issue.
We may want to log an email on the case requesting developer input without having to have all our developers be sugarCRM users.

And, in our environment, not everyone who submits a case should be a contact/lead/target in our system; yet we should be able to reply to them.

Is there a way to override the To, Cc and Bcc lines and have them simply accept an email address like any e-mail editor would?

thanks,
