I’m nubie in fuse, i want to create some living a book app (like Dark Forest). I’m confused how I can save/know where the last page user read. And can recall it back when app restart , so user doesn’t need start over again from first chapter. I’m using router in MainView.ux

You can use lifecycle in combination with FileSystem.
