Maybe no one will add a MIME part in this way; people (or almost
mail clients) add attachments at the bottom no matter how the body
is big.  Because of this, I sometimes overlook them.

The code in this attachment makes Gnus show attachments at the top.
`g' toggles the appearance.

I like the idea; what about adding an option to toggle that?

Making the attachments more visible is a good idea.  Would it make sense
to add a new "header" in the display that just lists them?   

Attachments: [button] [button] [button]

They could also be included where they are in the message like now, but
listing them twice shouldn't be a problem...

Thanks for the suggestion.  I've implemented this in the Gnus Git
master.  Now the feature is turned on by default.  If you don't
want it, set `gnus-mime-display-attachment-buttons-in-header' to
nil.

If you have the old code in your .gnus.el file, please remove it
anyway.  Customize `gnus-header-face-alist' as follows if you
want to change the appearance of buttons:

(eval-after-load "gnus-art"
  '(add-to-list
    'gnus-header-face-alist
    '("Attachments?:" Header-Name-Face Header-Content-Face)))

When you customize it, note that the element that begins with
"" should be the last item of `gnus-header-face-alist'.

I really like this change! One thing that seems a bit broken now,
though, is hitting "K o" from the summary buffer --
gnus-article-save-part. I tried it on a few different messages, and they
all gave me the same error, below. I haven't customized much in this
area, so I assume it's not a local issue, but let me know if you want
more information.

Debugger entered--Lisp error: (wrong-type-argument number-or-marker-p "2")
  gnus-article-part-wrapper(nil mm-save-part)
  gnus-article-save-part(nil)
  call-interactively(gnus-article-save-part nil nil)

Thanks,
Eric

Thanks for pointing it out.  I'll fix it, but after this weekend,
sorry.

I've installed a fix.  Could you try it?

Seems to be working fine. Thanks again!

Yeah, it's really nice.  97.3% of the time, the attachment is the main
point of the message, so having it at the start (instead of the end) is
a great improvement.

Thanks for the code, I have used it frequently since it was released.

However I just received a mail in which the author put his attachment,
*after* his signature and in this case your functions fails.

Do you want me to send you an example?

The email in question was sent using 

    -  Apple Mail, 

    -  as a HTMLized mail 

    -  and using  the no standard mail signature separator
--------------------------------------------------

I don't have a apple so the only thing I can do is to forward you the message in
question, but that I would prefer to do off the list. Your email address
however is refused when I send it to you, please tell me what to do.

Oops.  Sadly my e-mail addresses are sometimes black-listed
because of spammers who are under the assumed name of it.
Though it is expired from the list within a couple of days, it's
very annoying. :<
Could you send again an example to <yamaoka (at) twa.co.jp> ?

Thanks.

Done, I sent it in three different formats:

    -  gnus inline

    -  seamonkey (thunderbird) html, inline

    -  seamonkey (thunderbird) html, attachment 

Thanks

I've received those mails.  Thanks.  The revised code is attached.

I realized my fault was that the MIME parts that the code moves
to the top was only attachments.  In an example mail, but there
is an inline PDF part, that is not inlinable in Gnus normally[1].
So, I've changed the criteria so as to gather the ones that are
not inlinable in Gnus.

By the way, Lars suggested a way to show attachment buttons in
the header[2].  It looks much smart, so I'd like to try it when
I have time.

[1] Though it might be possible to display an inline PDF part in
    the article buffer by using docview.

Just like to note that won't work when, for instance

	(nnimap-fetch-partial-articles "text/"))

is set.

IIUC this, we have nothing to do for it.  (I'm not an IMAP user.)
