I would appreciate the option to place a double row of fencing, because it is tricky to place two fences tidily close together. To escape, a dinosaur must break both fences.
This could be implemented as a double fence at the time you place it, OR, use a similar mode to "Replace" when altering fence types.
Mechanically, it would just be two fences - the feature is just the tool that lets you place them simultaneously, with the same curve, and the game automatically scaling the inner and outer pieces to match. Possibly with a slider/option to set the distance between the two fences!
