The Pathfinding behavior is great and all, but sometimes you don't need Astar.
Sometimes all you need is the ability to make your own path.
My suggestion is, would it be possible to add to the existing plug by adding an add node action?
That way you could set up your own path(xy's) and get more versatility out of the existing plug.
Plus it might be very useful to add to the Astar path once it was found. Say for example you didn't want the object to go to the exact coords at the end of the regular path, but some random position close to it. Very, very useful for multiple units.
