Feature request: Move your last opponent to the top of the play area when a 3+ player game has only two players left

It could be great if the arrangement of players could shift when players lose; it could be confusing to do too much re-arranging when more than one opponent is still in the game, but at a minimum it would be nice if games that have become two-player games could automatically move your remaining opponent's board to the top of the play area. It was very inconvenient to have half the play area taken up with empty boards from players who lost, while my opponent and I were crammed into the bottom half of the play area.

More generally, if the top side of the play area ever becomes empty, it would be nice if xmage could rearrange the surviving players to make better use of the screen space.
