I'm playing with a character capable of using Thaumaturgy, and I wish there was a slight visual queue when a cutscene that involves dialogue was just ahead. I'm thinking something like an emitter coming from the NPC who will trigger the cutscene.
One particular example of when this would have aided me is the sing-a-long with the sad Tiefling bard just outside the Druid's Grove. If I had known a cutscene would occur before I approached to speak, I could have had my Thaumaturgy activated to help with my performance.
