I'd like a device that keeps all the cables straight and knot free, to foil the best efforts of the Cable Pixie who will get into your bag or drawer or closet and tangle up all the cables you have there. You know what I mean... those Christmas lights that you remember CAREFULLY winding round the sprockety thing, and putting into their own individual sockets.... the headphones you carefully stowed away with the cord in a loop.... all of them come out of the box or bag in a knot.
