So my tutorial is breaking the 100 lessons mark. It can be tough to make changes and review them. For instance, if I make a change to lesson 99 and want to see it. I have to go through all the lessons to get there - I don't think there's an easy way around it. It's manageable for now, since I am not needing to frequently go back and fourth. But I can see this being a real pain at times. I can deal with it if I need to.
