The saving of a pdf is a really nice feature.  I had hacked org-agenda, I think, to automatically do this.  However, it would be nicer if immediate display were optional.  I don't know whether \C-u makes sense as a prefix to saving a file with \C-x \C-w.  Perhaps not. 

Perhaps this cannot even be done at all, given the utter elegance of the solution that we are given. 

Thank you for this feature.
