neither "Use Orage window", now "Use notification" show any brief information about the date and time of an event that is being reminded about. At present to consider Orage usable I resort to "Procedure" notify-send --expire-time='0' --icon='stock_alarm' "`date +'%Y-%m-%dT%H:%I:%SZ'`" 'foobar' which isn't ideal because it doesn't give you a link to the "month view" or "day view", but at least displays important details without forcing me to open the main interface to learn more.
