That isn’t a negative though. You’re saying that it auto sorts downloaded content well enough that the user doesn’t even have to be aware of how to access the file manager to still use the phone effectively. That isn’t a flaw, it’s a feature.
For anyone who does have a baseline level of proficiency, the file manager is functional, and familiar. I use it to pass torrents to my server all the time.
With a terminal and a file manager on iOS, I don’t run into a single thing I need to do that I can’t.
