I agree on all parts - a clickable 'up next' link on the top right, and also a clickable 'previously you learned' link on the top left. Wording should change to fit the layout, of course.
Also some sort of hint that the ToC is clickable, I didn't realize that at first either.
Also, it strikes me that the entire guide should be put on GitHub - did I miss somewhere where it says it is?
All in all this is a great resource along the lines of http://hginit.com/ - which is useful, because the mostly brain-dead students at my university tend to take FOREVER to learn DVCSs. I can't tell you how many times I've had to explain that you really only need to 'git clone' once unless you are checking to make sure you got everything 'right' with the push.

Now instead I'll just point people at this.
