Well, you can use it as such, storing the notes locally with the corresponding title. You'll find a lot more on the SSuite, maybe there you'll find something els which may serve you, anyway good to bookmark it, it's pretty usefull.
But I also remember another app, an old Gem, OpenSource which may fullfit your needs, it's a very powerfull tree style note taking app, rich text format and if you need, also syntax highlighting for programming scripts. (Windows, Linux) (.rtf, .txt, scripts)
