I would love to see a Browse Document Hierarchy as a tab to find the new location when moving a wiki document using Edit>>Location. This is in addition to the "Search, History, Recently Modified, Referring Pages" tabs.

Its operation should be identical to the document hierarchy browser in a page's Info tab except it would need both navigate-deeper/expand and select functionalities. The end result, of course, is a reference to the selected parent document being inserted in the location field.
