I hate to complain about the sermon editor every week, I just keep seeing things I would like to improve as I use it.
When I type the sermon series in the sermon editor, it would be very convenient if it gave suggested completions, based on previous entries. So I do not have to worry about a typo or minor mixup keeping all of my sermons from being labelled in the same way. Also, venues should have the same feature, for the same reasons.
