This seems like a simple question, but I haven't been able to find anything in the docs or forums on it. Toolbar provides an event to let you know if the overflow state has changed, but once that happens, is there a way to know what items on the toolbar are on the overflow menu?

On this topic, any ideas about a config that would allow items to only be on the toolbar or on the overflow menu? This would allow toolbar items to be configured so that those that don't work or aren't appropriate on the overflow menu can either be suppressed or "replaced" by other items.
