Is there a way to make the calendar on the Today screen only show just one appointment? I have "Next Appointment" checked in the options, but it shows appointments for the whole day and even the next day. This puts a scroll bar at the bottom which I don't like. All I want is just the most recent appointment to show and once it has past show the next one.

Also, what is the Today timeout (default 4-hours) in the options screen?
