Layout of list of commands, views, and sitemap.

Hi. I'm working with the Pier 1.2 image from piercms.com, and I'm getting fed up with having to scroll down the web page every time I want to click on a command, a view, etc. So I've been trying to change the layout to be more like what I've seen on Pier sites in the past, where the commands, views, and sitemap were in a column down the left hand side. To this end, I've edited the environment to include: <div class="column span-6">+/environment/footer+</div> ... and set the contents div to "span-18 last". While this does get things approximately where I want them on screen, the list of commands etc are still being rendered horizontally, and wrapping around inside the div, which is a kind of a mess. I can't figure out what I should do to make them display neatly, one item per line, down the column. Any pointers much appreciated. Cheers, Nick Brown
