Not every time chapter needs to be reread! Sometimes we just go back and fix small errors or we try to make better directions. For this reason readers don’t have to reread same chapter.
Give authors option to decide, if reader has to reread last chapter or not.
You could do it similar as you did with Completition Status.
Honestly it can be a bit annoying when you have to re-read a whole chapter again because of the little details and edits the author/writer makes. I support this
Oh, I hope they really are working on this. Rereading because of branching/coding mistakes is fine, but having to reread a 15 minute chapter because of like… an extra comma somewhere? Or a layering mistake? It sucks.
I know some authors remedy it by making a choice that skips you to the end of the chapter, but if you have a lot of meaningful choices, gains or character points, you can’t use that trick without a major headache.
