CiviMail - Allow Preview of Email Subject

From forum discussion:

How do we preview the Email Subject?

What is the most important content line in an email - maybe the subject? Am I missing something or are we unable to preview the message but not the subject.

The email subject defaults to the name of the mailing, which is good, but means that the subject must be tweaked and we sometimes forget to do this and can't seem to preview the subject until the email is sent.

Is there an easy way to preview the subject before the email is sent?

Thanks.
