Any idea how to add optional CCs? That is...only show the CC line if there is at least one CC recipient.

Edit: Never mind. I got it. Basically...after the To line ends, put a { followed by a line break. Then insert your CC line per usual, ending with another }. This essentially only breaks line and inserts the CC line if the CC recipient exists.
