Comment (by westonruter):

 In [attachment:28709.wip.7.diff]:

  * Rename `onToggle*` to `onChange*`
  * Move `WidgetControl` duration to `defaultExpandedArguments`
  * Short-circuit `expand`/`collapse`, `activate`/`deactivate` if already
 set
  * Make sure `Control.activate`/`Control.deactivate` take params
  * Update `WidgetControl.collapse`/`WidgetControl.expand` to accept params
  * `api.Section.focus()` and `api.Control.focus()`
  * Support `allowMultiple` option on `Section.expand()`
  * Factor out duplicate logic from `expand`/`collapse`,
 `activate`/`deactivate`; always call `completeCallback`
  * Expand contained panel first before expanding section
  * Update `Section.focus` to build upon `Section.expand`
  * Consolidate `focus` into one shared method reused by Panels, Sections,
 Controls
