Make it possible to add highlights to the rerun while the rerun is being played
I work for a Gaming News organization and we stream 6-7 days a week and have 2 people running our rerun. Sometimes the order gets screwed up or someone forgot to add a video in the line up and its not possible to add or subtract from the rerun when its playing. Being able to move things around (obviously no the video being played) but ability to change on the go would be very valuable to my job in particular.
Being able to manage the rerun queue while it's playing is pretty essential. Having to wait for the end of the queue to add anything is awful, especially when one of the uses of reruns is to have something playing when you're not able to stream.
