How to allow collection items to be re-ordered?

With the latest cockpit version, how can you allow collection items to be re-ordered by a field or drag-n-drop custom order? The previous version had a feature where the user could drag-n-drop collection items to re-order them and also allow order to be by a field.

If you create a content model, select the tree model type.

Is there any reason why the collection model doesn’t allow reordering. The tree model mentions it’s more for parent/child relationships. But I’m using a collection for things like news articles lists, team Members, etc.
