Agreed, I like to have my sequences trigger based on genre also. Horror movies have a halloween-esque sequence, action movies have an action sequence, etc.
Along with this, different music for different slide decks, Horror may have scary music, whereas an action movie may be playing a james bond theme or some generic action tune
And also, be able to handle multiple different slide decks, for example, a freddy slide deck and a jason slide deck and be able to shuffle them while still maintaining the q and a order
