Vobs need some more thinking: in the end it turned out that the key 
paradigm made PP actually more *DIFFICULT* to implement; the key paradigm
currently doesn't allow enough fine-tuning. For PP, we want to take more
control, say "animate X to Y", i.e. the particular view that was clicked
should be the one to animate to the center.

True, this is important; vital to get performance tuned right for PP.
