Penalized crossed connections?

[alinsavix]

I use the 'arrange nodes' button pretty often, and there's a pretty good percentage of the time where the final positions chosen has one or more connection paths crossed with each other -- even if the starting position didn't have any crossed connections. Since having crossed connections is almost always worse than not having them, it would be nice if node relax could penalize that in some way so that it would not be the preferred way of arranging nodes unless it really provides a significant layout benefit.

(awesome addon, btw! <3 )
