Currently when a document is added to Evernote, if it is a type that is "displayable" for Evernote, it is presented as viewed as "single page."
Some users that use Evernote for the sake of organization store/accumulate documents continually. When such documents are many can make the notes long, and rather impossible to read/follow.
I think that it could be a good idea to be able of requesting for a note to have all documents viewed as "attachments," "single page," or "all pages," once this is performed in the note, then the user can select to change one of the documents at will.
