Version 9.0 has been improved with the ability to define an additional popup reminder or desktop alert for an event or task. Instead of being based on the event or task starting time, this additional reminder is based on the event ending or task due time.
How to Configure an Additional Reminder
The "Show a popup reminder" and "Show a desktop alert" reminder settings in the Event and Task Editors have a new "Before event end" check box. To enable an additional reminder based on when an event ends or a task is due, check the box and then enter the desired time.
If you'd like to always have an additional reminder, this can be saved as a default by clicking the Defaults button at the top of the editor window (to the right of the Email button), and picking "Save as Defaults" from the drop-down menu. Note, the "Save as Defaults" command is not available in the Lite version.
When an upcoming event or task has been configured with an additional reminder, this will be indicated in the Details pane.
In the example above, an event has been defined starting at 10:00 AM and ending at 2:00 PM. A popup reminder will first be displayed at 9:45 AM. If the reminder is dismissed before 1:45 PM, an additional reminder will be displayed at 1:45 PM. Otherwise, only the one reminder will appear - dismissing the reminder after the end of the event will not result in the additional reminder appearing.
To make room for the additional reminder settings, and to help reduce clutter, the reminder content settings (song, media, web page, voice reminder, etc.) have been moved to a new "Content" tab. These features are still supported and have not been removed. The same content will be used for both reminders, so the desired content only needs to be specified once. Again, the content settings can be saved as the default by clicking the "Save as Defaults" command at the top of the editor window.
