According to reports, iTunes 11.1, which released as part of the developer preview of iOS X 10.9 Mavericks, has a new app screen organizer.
It now shows the Home screen layout with the screens side-by-side. This makes it easier to move apps around it. In the past, it was a little more difficult, because you had one screen and had to drag icons horizontally to change pages. It wasn’t the most enjoyable experience.
It’s strange that this was never done before, but at least it’s fixed now, and it will be a much better way to organize our apps.
