Improve reordering UX: Placeholder for position while dragging
This is kind of a follow-up to #412.
Reordering things works now, which is great. But the feature still is quite hard to use, as it is hard to determine at which position an item will be after you dropped it. This sometimes leads to confusing results (e. g. you expecting the item to be in a different place than where it actually lands).
It would be nice to have a placeholder (e. g. a thick line, or just an empty space with the same height as the dragged item) while dragging at the place where the item would be if it was dropped.
