Once the create file button is clicked, it grays (on downloads under my assets), my 690 MB Audio Book mp3 was downloading in the background, but I had no way to know that --no spinning wheel, status bar done to show me what the heck was happening with my download, just a non-responsive grayed "create file" button. When I came back an hour later, both create file attempts magically appeared on the list and secretly downloaded in the background with no communication. Communication from the UI here would prevent user FRUSTRATION! Thanks
