This is not a high priority, but it would be nice if Hype could recognize markers in audio files. It's easy to create them in an audio editor and it would certainly help with triggering actions.
Another great feature would be audio triggering. - a tool that can track frequencies of an audio track in three bands, with separate sensitivity controls. The user can then set an action to watch one of the three bands and then be triggered by the peak. This is common with motion graphics apps.
