docking

I'm not sure about Fences 4, but Fences 5 allows unform spacing.

I see these options but not sure it's working properly. I have 38 fences over three monitors but if I use the setting shown above it merges everything into 3 Fences. I just want to snap the existing fences to equal spacing.

That's strange. It's possible this is a multi monitor issue. I don't use multiple monitors, so I can't test this. On my monitor, it only snaps existing fences a specified distance (10 pixels in my case) from each other.
