We blank our projector between songs/readings, so it's not distracting. Other churches will no doubt do the same, whilst others will feed in a video stream during those segments.
In order to do that, you have to create blank slides between every service item, which quickly gets frustrating. It would be great if Proclaim added a checkbox which said "Add blank/logo at the end". That could be part of our templates etc., so Proclaim would just remember that setting and we wouldn't have to add half-a-dozen blanks into every service.
