The TreeView derivatives allow reordering the children of a node using drag and
drop, but the ListView lacks this important feature. The users of EntPack need
to use the kludgy "reorder" action dialog instead of the natural drag-n-drop
technique for reordering nodes.
In particular, the TreeView indicates, by drawing a thin black line, where a
node will be dropped between two other nodes. This allows for easy reordering of
the nodes. ListView always assumes that the drop will occur inside another node,
not between nodes.
Reassigning to new module owner Tomas Holy.
Provide a patch, please.
