Cant belive it took me 2 months to reply to this. Very sorry about that.
I don't really see a purpose for a movie room.
I'd love to add a fanart room. But I don't really get fanart anymore. In fact, most of the artwork around the school is just mine. Also, most of the fanart was made by old friends that would not want their art in my mod.
There will be at least 1 new notebook in the future that will be used for the secret ending in a future update. Also, some future plans I have may increase or decrease the amount of notebooks but I'm not 100% sure if I am going with those plans as of now.
Anyways, thanks for the suggestions and sorry for it being 2 months late.
