Rated 5 out of 5 stars

Usefully allows editing of IMAP iOS Notes viewed in TB so the changes can sync back to an iPhone.
The ability to create notes would be nice!
Perhaps just change the error message, that occurs when trying to use the add-on on an email message created in TB, from "This does not appear to be a valid iOS Note" to a choice of "Convert to iOS Text Note" or "Exit" and add the functionality to add the header line "X-Uniform-Type-Identifier: com.apple.mail-note" to the message header.
But I guess you would also need some instruction directing the user to first create the message in the Drafts folder then move it to Notes. Hmm... not as easy as it first appears! Adding a dialogue to the "Write" button allowing a choice of email message or IMAP Note looks hard to do!
