Firstly, love the theme - thanks for the hard work that's gone into this.

Is it possible to expand/collapse the menu structure on the left?

While I'm at it, is it possible to reduce the font-size a point or 2 for the left-menu structure. Many titles are wrapping over 2 lines, but with a font size slightly smaller, this wouldn't happen - at least for the words I'm using - is this a CSS thing?
