Better Fences
Better fences overrides default fences and walls and replaces them with 2 fence types, one which connects to all nodes and one which only connects to other fences and walls.
Whenever you place or dig a fence, this mod will determine if the fence you just placed will connect to 2 or more adjacent fences or walls, if it will it places the fence which only connects to fences, otherwise it places the fence which connects to all nodes. Every dig and place will result in the surrounding 4 fences (if they exist) being checked and updated if necessary as well.
This behaviour results in only the fences at the end of a line of fences connecting to all nodes
There's a bug
you can't craft fence with planks, instead it only count two sticks to craft fences
