I've found using the "Lab" background in NoteBook to be difficult. The loud blue lines just get in the way of easy readability. About the best I could do is use Arial Rounded MT Bold as a font, but even that clashes with the blue grid. Reading paragraphs of text just isn't easy. What fonts or style do anyone else use with the Lab background?

Also, how do you put in a horizontal separator line between entries? That would also help distinguish entries in an outline. I'm using highlighting now, but I'd rather save that for pointing out text than as a separator.
