After using this for a couple of days, I've decided that I don't like the narrow width of the code examples. It looks like the code is being crammed into about 40 columns. It has to be fiddled with to get it formatted to fit and you still up with odd line breaks.
Overall, I like the colors and the general appearance, but the narrow format of the messages looks odd and cramped.
