Also I really liked that documentation thing someone showed us a while ago... It put code on one side and annotation paragraphs on the other, and despite being very simple I think it did a very good job of making the code and annotations easy to read.
 Oh nevermind, I understand.. the colors indicate a block of lines that relate to a single comment. I think that would be clearer if the color didn't break between every line. It's still tricky mousing over things though. If you go straight down from one line to the next, the comment doesn't change. You have to mvoe away from the text entirely, then back onto the line you're interested in.
