Dynamic Menu Highlighting in Kubrick

I am using WordPress as content management system for my site https://www.fmueller.com. I am using the Kubrick theme, and the sidebar is created by the following code:

<ul><?php wp_list_pages('include=6,7,8,9,90,91,71,63,577,75,65,103,258,105,271,603&title_li=' ); ?></ul>

Some sections of my site are becoming rather large, and a lot of people enter the site via sub pages. I would like to make it as obvious as possible for visitors which section of the site they are in. I’d be grateful for any suggestions how to best do that, but first of all I want to use Dynamic Menu Highlighting. Is there an easy way to do this and still use wp_list_pages for the sidebar – maybe even a plugin – or do I have to create the sidebar using a standard list?

Many thanks

Frank
