The Events menu needs a current clock, listing both AM/PM and 24-hour time in PST, as well as client-side system time. Have the client grab the system clock and if it's within 10 minutes of the servers, assume the user is in PST.
There should also be a way to indicate (IE, in different colours, a different column tag, etc) which events are currently in progress, have already completed, and are upcoming.
Finally, there should be a better mechanism for tying events and event messages together. Maybe letting us embed data within an IM, like we currently can with notecards? That way someone could just click on a link within an IM to get a landmark.
