Subject: [PATCH] Improve copying and moving items between panels

Currently, copying the selected items between panels is performed by the active panel, which is wrong, because the inactive panel cannot select the copied items after the operation is completed (as it happens when drag'n'dropping or copying using keyboard shortcuts).
