HI Graham,

Thanks for the constructive comments. I think we are approaching
consensus, which is great. Brief responses in-line

1) I'll let the editors Luc and Paolo comment on this one. This seems
doable from my perspective but I don't know what the effort would be.
2) This also seems like a good idea and I think others have commented
positively on having the diagram upfront
3) Again, I think I'll let the editor respond but you make a good argument.
4) I think there's consensus that "advanced" is not the right term.
5) Modularity + 1
6) My tendency would to be think that cross referencing is always nice

Thanks again for your quick response!
Paul
