Use case would be revisiting a table after a while of not using it and needing a very quick understanding of how it works. I know there's a map view but sometimes I have 2-3 columns of the same info from different sources and I just want to know which column belongs to which parent without having to right click. Also not a fan of it dragging me over to the parent column because it makes me lose my spot, especially if the parent is on the other side of the table
