Why do you store the visual node positions? For me it is hard to imagine anyone want to edit those. Why not just automatic layout?

I would like to subscribe to the news, but am afraid to use news-letter services. I suspect they sell the addresses to spammers. Would you please instead set up an atom feed or a primitive blog on Blogger?

This sounds bad. Any info in the text related to the visual representation will be unreadable i guess. Hiding such for diff review is helpful but not enough. Because in merge conflict resolution one may not have the luxury to neglect it.
