If you are annoyed with consumption of large amount of window space by page, category, and archive list, this plugin will be useful.
When the bottom of the menu seems to be out of the window, the menu is “multi-columnized” automatically. Also, when the right side of the menu seems to be out of the window, the horizontal position of the menu is 
automatically adjusted.
You can change font-size, color, spacing in the admin page easily.

This plugin creates two taxonomies for categorizing pages, and their respective archives.
Upon activation, two pages are created that serve as the top-level archives. They are initially named ‘Categories’ and ‘Areas Served’, but may be updated to suit your needs. These pages will display a visual category selection that link to paginated listings of all the content pages associated with each taxonomy.
Pages can be easily assigned to the custom taxonomies by using the checkbox options added to the Edit Page admin area.
<h4>Custom Categories</h4>
This taxonomy is intended for products or services, for example: “Bathrooms,” “Kitchens,” “Outdoor,” etc. All categories in this taxonomy will exist as top-level items (no parent/child relationships).
<h4>Areas Served</h4>
This taxonomy is intended to use US cities and states in parent/child relationships, for example: Texas > Dallas. Properly setting up these locations will allow the Areas Served archive page to create separate state pages with a sub-listing of all its cities.

Socius Marketing Page Taxonomy

Adds 2 custom taxonomies (categories & areas served) to Pages for easy, dynamic archive listing.
