Drag and drop blocks in details preview

When putting together the details view for records, it would be nice if we could easily drag and drop the boxes into the order we want.  It is such a pain to have several blocks arranged just how you want them, only to realize you need to move (or add) a block to display in a different order.  

Mind you, the drag-drop might prove to be cumbersome (especially if they are large blocks containing many fields), so perhaps an up/down arrow set to allow you to sift the block up or down as needed.  

Also, when you add a block (or add related block), it should add to your list under the block you have currently selected.  

These features would be a HUGE help!
