See who opened, confirmed, rated, denied a swap

It would be nice to see in your swaps monitor, who (I, or the other) opened, confirmed, rated or denied the swap.
A nice way would be to split the light, middle, darkblue, green, and red parts in an upper and down part, for "I" or "the other". Opened and denied could only be colored by one of these parts, the states: under discussion, confirmed and rated (hopefully) will finally colored by both.
