#661 , is it possible to automatically populate the end date of the panel with the date/time chosen for the start date + 1 hour? When I went to set up mine, I picked the start date and the end date was months prior, so it gave me an error. I expected the error, it would just be nice to pre-empt that. If this is indeed possible, we can put it in a new ticket.
Also, the widget populates military time. It would be nice if it showed AM/PM instead. Again, okay to put in a new ticket.

#668 looks great. I discovered that I get an error message if I try to export when one of the reviews is incomplete. We should probably examine that

#676 I don't see these?
#669 I don't see this either
