As the page currently stands, it has 2778 single-line rows in my browser. If I add section name column, this number goes down dramatically, to 996. Even at this level the table height will grow by 30% if we do that.

These numbers make me think that we should try to preserve row height. I'm not sure if there's a good way to break up section names, but even at my 150% scale there's blank horizontal space which we can widen the table into to compensate for the new column. What do you think?
