What happened to the 'Drag To Rearrange Panels' feature in v1.0?

You can still replace and order the panels how you want by tapping on any panel and selecting the right replace button. However, Apple contacted us and requested we remove the ability to drag and rearrange panels, because this is in violation of section 10.4 "Apps that create alternate desktop/home screen environments or simulate multi-App widget experiences will be rejected" of the App Store Review Guidelines. We hope Apple reverses their decision in the future on this useful and natural UI feature.
