I've significantly improved the drag and drop experience! The left column question types are now sortable, allowing you to reorder them as needed. Most importantly, I've enhanced the middle column drop experience with visual drop indicators that show exactly where items will be placed - you can now drop questions between existing questions for precise positioning instead of always landing at the end. The system also provides better visual feedback with enhanced drag overlays and smooth animations.

I've fixed the drop functionality by adding proper droppable zones between questions. The new DroppableArea component creates dedicated drop targets that provide visual feedback and handle precise positioning. Now you can drop question types anywhere in the middle column - at the beginning, between existing questions, or at the end - with clear visual indicators showing exactly where the item will be placed.
