Yes Quiver has a very simple hierarchy: notebooks and notes. But you can use tags and linked notes for more flexible note organization. Also, when there are lots of notes, the only practical way to find something quickly is a full-text search, which Quiver supports nicely.

Whoa.. is the full-text search per notebook or every notebook? Can I choose to search per notebook and every notebooks?

That sounds awesome!
