Would like more thorough recording of outgoing emails

Every time an email goes out (Response, Note, or Scenario), we would like a recording of who was it sent to (To, CC, and BCC), and what did it say. One cannot assume that the scenario has not changed, or that group membership has not changed (also, cross-correlating the main ticket with the Activity log is tedious). Ideally this information would all be integrated into the the main ticket record. Perhaps, to avoid clutter, it would not be expanded by default, but any given entry could be expanded with a click.
