Explain the problem as you see it
Enable manual reordering of nodes in search results... Also, when the search results are grouped (e.g. by status), enable dragging between groups to change the properties of the node being dragged.
Why is this a problem for you?
Being able to manually organize tasks is often a lot more effective than trying to find the right priority or other sort order.
Suggest a solution
Allow manual, drag & drop, reordering.
