Currently, if a heading in the Table of content is very short, it can be slightly annoying trying to hit that particular heading. I suggest changing the CSS to something like this:

 #toc li a { display:inline-block; width: 100%; }
 #toc li a:hover { background-color:#e8e8e8; }

The hover effect would make it easier to see which particular heading you're going to hit, without being too obnoxious, and stretching the list links to the whole box width would make it actually easier to hit the heading you want.
