Really tough to use. The fullscreen button just shows a static image fullscreen, so you can browse the whole set in fullscreen. Even at fullscreen, the text is blurry and tiny and the diagrams too complicated. I know a little bit of the language, but don't even want to attempt it. Without fullscreen, it's impossible.
