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.
Yes, this is valid enhancement and makes sense.
Coded in Orage 4.7.6.5. Available in git.
