Are you kidding? If I had a tuppence for every time I fished I had such a feature in my digital camera...! Nothing fancy - after all, I am not going to author DVDs on my phone. No, that would be silly. But consider just a couiple common use cases:You've made a longer clip so as not to miss some action and want to cut a lead/tail/middle off; You've made two short clips and want to stitch them together...
