This feature allows you to highlight a particular session that you plan on making available to the event attendees to keep accessing after the event is over. This would help the attendees easily find the content you make available after the event.
How to highlight a session
Navigate to the Admin Panel - content - schedule
Select the content slot to be highlighted and click edit
Under: Highlight this session once the event has ended. Position from 1 - 6.
Once you are happy with the placing number, save the changes.
After that, the schedule in the Admin Panel will have a new column helping you spot the session highlighted.
These will only display on the home screen in the selected order once the event is over.
