-// TODO: We should have a separate 'state.json' file, which remembers jack connections, and the world time for the show to end. Then we only update the 'time remaining' field in the scene and only deal with relative durations inside the scene data
 // TODO: We should be able to delete entries from the conversation, or at least go back and edit something I said.
 // TODO: I want a "mark" command or keyboard shortcut, that inserts a marker into the log, so I know where to come back for the next speaking segment.
 // TODO: If we insert text without speaking, this should be indicated visually somehow
