I know it has the times for scheduled recordings but it would be easier to cue in on if they had a colored bar on the side of the recordings that share time periods. The bar could start shortly below the top on side of the first recording but stay solid until shortly above the bottom on the side of the last recording. I would include it whenever they overlap such as 1 could be a 2 hour recording while you also have 2 others that are 1 hour but different hours but still in the 2 hour frame. I wouldn't use any padding in the determination and wouldn't connect them on actual time if 1 ends where another begins. (show 1 ends 10pm and show 2 starts at 10pm then no connection is made.)
