Usability enhancements for Drupal hierarchies (menu links and taxonomy)

Overview

The navigation menu, breadcrumb links, primary links, etc are important for users to be able to navigate your site. Is the way they work in Drupal 6 optimal for usability? Are there better default behaviors we could build for Drupal 7? Could we better accommodate non-standard browsers (e.g. screenreaders)

Agenda

* Fixes up to now (e.g. http://drupal.org/node/270917)
* Default markup
* Your suggestions and input!

Goals

This session will focus on Drupal core, not on contributed modules which can alter or enhance the built-in menus and taxonomy.

By identifying usability problems and possible fixes, this session will hopefully result in some fixes being identified to be addressed in core.

Resources

You should have used a Drupal 6 installation and thought about how you navigate using menus and taxonomy, and how you arrange or assign menu links and taxonomy terms.

If possible, think about "scalable menu parent choosers" and hierarchical select widgets. See: http://drupal.org/node/191360
