Annie Sexton: I guess you might want to think about whether you want to allow that. It breaks the model, in my view. For example, it means saying foo/bar (or /foo/bar) doesn't necessarily identify a note because there might be two folders foo, each with a note bar. I get that the database doesn't care, but you're leaning on an known structure with assocations, on of which is that folder names are unique within each parent folder (including the root folder).
