A video scroll or scrubbing bar that could control a video and other objects at the same time would be a dream come true. For example, as the video of a presenter plays, graphics such as a presenter's powerpoint slides could pop up. When you grab the scrubber and move it back and forth, the video and the slides respond appropriately. As a non-opus script enabled unit, I'm going nuts trying to fudge something up.
Even just a scrubber for video would be good. I've down loaded examples but had no luck inserting them into productions.
Still, Opus is one of my favourite programmes.
