Hi JD,
	I could.  I definitely wouldn't want to call it "binding site" since  
it includes waters and residues not necessarily involved in binding,  
not to mention the entire structure for small-molecule structures.   
It's also a misleading name for structures without ligand present --  
since their binding sites won't be selected by it.  FInally, it's also  
somewhat confusing as to what should happen if you open multiple  
structures over the course of a session.
	So it could be called "smart display atoms" I suppose.  If some other  
users thought it'd be useful I'd do that (anyone?).  In the interim,  
you can pretty easily create the selection yourself with these  
commands after opening the structure:

	sel @/display; namesel smart atoms; ~sel

You could alias that to something snappier. :-)
