You can do a "To Front" on the display from its view menu. This essentially 
moves the display to the front (or back?) of the list of displays, removes its 
displayables and re-adds them thus changing the rendering order. Is this not 
working for you guys?

As to the DND for changing positions - we have thought about doing that but 
just haven't because the explicit to front seems to works fine. Go ahead and 
have at it if you'd like.
