Feature Request

I need to be able to iterate over Notes. The usefulness is limited otherwise, at least for me. I would have to walk the directory tree and get individual Note objects.

Maybe it's possible but I can't tell but I would also like to be able to filter by tag but any value other than None should match, in other words the second argument to has_meta should not be required and should match anything, None should also be an option for when the tag exists but there are no values present.
