Well, 
I like the way some EDA programs do the following:
if you select a part in the PCB editor, it is selected in the schematic
too, and vice versa.
This is usefull when you are placing components by hand in the PCB and
you don't remember what was that part related to.

But I can also live without this by now.
Just a thought.
