The search in this thing is incredible. Definitions come up, context comes up, even get results from the material in the linked resources. Really cool how easy it is to navigate--if you click a link to go to another section of the text, back arrow brings you back where you were. That really makes it easier to learn what you don't know, like flipping back and forth to a glossary or footnotes in a book but without any hassle.
