Oh well, I was pretty certain that another request for a similar feature would have had to have been made but I could find it in Super Search so I figured I'd ask nevertheless, just in case... Thanks for the pointer to turnstep's page, it's a truly useful resource.

update: no I didn't misunderstand kudra's answer and indeed I think it does help to increase the number of cross-links between nodes (the density of the graph if you want).

I really need to grab the Everything source and have a look at how it's done to start patching. Good thing that vacations are coming :)
