I don't know if this is something that can be fixed in xfmedia or upstream, but I can't reorder 
multiple items.  If I use the SHIFT key to select a group of files (e.g. an album's worth) and 
move them--even while holding the mouse down--only the last one selected is moved.

Great programme though!  I was reticent at first to accept YAMP (yet another media player) 
but I should've realised that it would be a good one since it's Xf*. :-)
