Hello,
I hope I'm not polluting this mailing list wrongly (due to org-mime
being contrib and not mainline).
I wrote a small patch that gives the function org-mime-toggle-html
(+ support) for that I had to unfortunately rewrite `org-mime-multipart'
Maybe Eric can look at it and if useful include it.
