Further changes:

    A mounting hole in the middle of one edge to allow for easier bed leveling thanks to Nophead for this suggestion.
    Larger LED and Resistor pads to allow for 1206 size surface mount components.
    Much larger area to solder the current carrying wire, easily connect ribbon cable (such as with the Mendel90 headbed connection). Also the through holes increased in size.
    The redundant pads on the non-heating element side of the board removed to prevent confusion. These are not electrically connected if the board is not plated (plated boards are bad for the reasons outlined by Josef Prusa above).
