Nice feature to implement in future releases

It would be nice that if you hovered a file over a folder the folder 
would open up so that you can place it in a sub folder if you wish, and 
if you hovered it over a place, that place would open up in the right pane.

It was one of this things I liked about the MACos. It would be nice if I 
could get it in nautilus.
