Feature request: D&D list item onto another list item

I can currently reorder lists by dragging and dropping between existing list items. What I’d also like to do is drag a list item on top of another item and have the dragged item nest under the item being dropped onto.

Also, when I reorder an item it becomes selected and I have to de-select it if I want to edit it or check it’s checkbox. If I don’t, I get a drop down menu
