item selection in one content view should be reflected across all views. I.e. say you select item /some/path in tree view, switching to list view or thumbnail view should display that item selected which currently does not happen: initially no item is selected in the other views that is path is root, therefore the selection state is already inconsistent. Currently, selecting any path on any view means you end up in an inconsistent state where different views have different paths selected and url in location bar is correct only for the last selection.
