It would be nice if you could abandon a chapter. If you start one and then change your mind and wish to skip it, by progressing the story line, then the ability to abandon the old chapter should exist. If I start on the Hutt Cartel and later choose to just skip it and hop to the Eternal Throne, then the chapters before that should be able to be abandoned. You already make all decisions for my character if I skip a chapter, so why not factor in the ability to abandon the chapter you are skipping.
