I think from the perspective of an editor feature it would be enough to 
have the editor insert arbitrary padding between the systems. In such a 
continuous mode we don't care about system to system spacing with regard 
to page formatting. But I agree that having some notion of a "natural" 
top and bottom padding of the systems would be good to have.
