EnhanceMail also alters the behavior of Mail in a few other minor ways.  As these are regarded as unambiguous Good Things (at least by the author), there are no options for them.  Users which don't approve should easily be able to just ignore them.

·	EnhanceMail inserts a small message giving its name and version number into the Mail Info panel.

·	EnhanceMail reenables the disabled Mail feature of flagging.  This allows you to mark messages in addition to read or unread.  EnhanceMail also fixes a small Mail bug which heretofore prevented flagging from being persistent.

·	EnhanceMail adds a X-Nextstep-Mailer header to all outgoing messages.  This header indicates that you used Mail and EnhanceMail to compose the message and their respective versions.

·	EnhanceMail adds a In-Reply-To header to all replies.  Some mailers use that header to thread mailbox contents.
