When demonstrating the power of typo today to someone, they asked if there was a way to add a navigation bar with a menu to the site. Essentially this would expand the flexibility to Typo to be a cheap way to build entire websites with rich navigation. The power is there by utilizing categories and pages to populate the menus, then simply adding a navigation option either in the sidebar or in a separate div to be placed via css.

Another way to implement it is to take the pages sidebar and separate it to a separate div that controls another div through JavaScript to change the content depending on which page is currently active.

Enhancements such as hover and layering could also be added to make the menu pop open contents. Given that the current thrust is for separating JavaScript from the main engine, this would probably be best implemented as a plugin option, however, some admin controls could become necessary at some point.
