Thanks for your response. It's great to hear that Evernote for Windows is working properly in this regard, but I can confirm that the Evernote web-based client, as well as the current version of Evernote for Mac (v7.9.1) does not do this. If you create a new Note using either client, and insert text only in the body, the title will always display as "Untitled" in list view.
If you open the individual Note to edit the title on either the web and Mac clients, both will recognize the title field as blank, which is expected behavior. But if you edit the same note in the iOS client, the title field shows up as being populated with the word "Untitled," rather than a blank field. Creating a new Note in the iOS client, however, properly populates the title with the contents of the note.
