Glossary entry for _Toolbars and similar containers_:

A collection of commonly used controls presented in a region that can be
configured or navigated separately from other regions. Such containers
may be docked or free-floating, permanent or transient, integral to the
application or add-ons. Variations are often called toolbars, palettes,
panels, or inspectors.


Mark proposes the following for 2.8.1, accepting Greg's proposal for the rest:

2.8.1 Configure Toolbars: The user can add, remove, reorder, and reposition any toolbars and similar containers of controls, as well as the items contained within them, in the user agent's user interface. (Level AA)
