Those are forward/back “browser” buttons, not sort buttons. There is no way to sort the Binder in iOS Scrivener.
It is possible to sort search results, which may or may not be helpful for what you’re trying to do.
Note that the Binder does not work like a file manager: the order is defined by you as the author, and in most cases applying an arbitrary sort order would be a terrible idea.
Hi thanks for your reply. I’m trying to reorder a folder not the binder. But I guess that may not be possible either. I’m wondering how the greyed out arrows can be activated and what they are for within a folder.
