Got a lot more of the navigation stuff working, fixed a few bugs, optimized and cleaned up a number of items as well.
Changed the graphics for the navigation nodes to something a little bit more interesting. Also changed some behavior slightly to solve a few issues and to make a few things a little bit easier to work with, when it comes to managing these nodes.
These nodes are now grown from the root which can only be created in the navigation mode. From there, you can edit them, remove them, attach proximity and timer triggers to them and control the activity state of each branch.
Turn the root node on and your active machine will follow this route.
Best keep working.
