Notational Velocity – An interesting OS X note taking app. As stated on 43 Folders, “All Notational Velocity does is record little notes, but it does that in a way that is completely elegant, intuitive, and incrementally searchable. It does this by an uncanny dual use of a single text field for both searching and creation of your notes. If you’re just typing in the field, it acts as a full-text, incremental, live search on all of your notes and their contents. If you hit RETURN at any point, you generate a new note with its title set to whatever you just typed.”
