Once you save the screen you go to has the chapter list with edit and preview options.
Below the chapter title is the button to add a decision and tell it which chapter you will be going to if that decision is clicked.
The story tree does very clearly mark anything still in draft mode which will be really nice if you are publishing chapters as you go and end up with a long story.
I added Me as Me in the cast just to see what happens. I do have the option of altering and updating that as well as deleting.
