Usability - Drag an item in between

[Quantum7]

Problem:
1. I select an item with the mouse (i.e. A).
2. I want to move it in between two other items in the tree (B and C). So I start dragging it.
3. I can't seem to do that. If I drag it to B, it gets added beneath B, if I drag it to C, it gets added beneath C. If I drag it to b's parent, it gets added to the bottom of the list of B.

Low priority suggestion:
The ability to have a horizontal line between items to which can be dragged. That would insert it there.

Notes:
- This seems more useful if the list is longer.
- I might be missing a way in which to do this ofcourse (didn't see a suggestion about it yet though).
