Is there any way to have the UltraWinTree control provide feedback on exactly where a node is going to be dropped, especially if there are multiple levels of nodes? It would be useful to provide some way of knowing exactly where you're dropping a node, especially if it's at a boundary of two nodes at different levels in a hierarchy.
Even something like a horizontal bar right in the tree that shows the expected drop position would be very helpful to users. I've tried looking around for examples of this with no luck.
There is a sample that is included with the SDK, 'UltraTree Drag and Drop', which demonstrates exactly what you describe here.
