Enhance drawer functionality
1. make drawer contents deep-linkable from other pages, so that the link action opens the drawer automatically
2. get rid of the Expand All element when there is only one drawer; make this optional on all groups of drawers
3. make drawers linkable from menus and other navigation elements
4. make drawer contents reusable
Re 1&3: Rougly this is already possible.
Navigate to a site that uses drawers and -- keeping an eye on the URL in your browser window -- click a drawer. The URL changes to add an anchor (#) tag when you open a drawer. Generally, the anchor is "#<Title of your Drawer>" Add that sameURL+ anchor as the target of any hyperlink, and clicking the link will take you directly to the page with drawers and automatically open that drawer.
