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!
