Our plan is to completely rework the “Move Items to” panel into a full fledged outline view, where you can either select a new target by double-clicking, or where you can drag items from the main window into, while the main window’s outline view retains its current scroll state.
I believe David wants the outline view to stay at the same scrolling position, no matter where he moves the selected items. Right now, the outline view jumps to the positions, where the items are moved.
