A note, or selection of notes, can be re-arranged in Outline view by dragging the selection to the desired location. Keeping the cursor over the right part of other note names in the view, the user will see a green rule between existing notes indicating where the dropped item will be placed. The degree of indentation to the left edge of the rule will indicate where in the hierarchy the dropped note will be placed (i.e. as a sibling or a child of the note above it).
Note that dragging a hierarchical selection will flatten it at point of re-insertion in the outline; the selection collapses into outline order sequence.
Dragging note(s) will alter their $OutlineOrder and other outline-position related attributes.
