<p>The node can be connected to any <code>link out</code> node that exists on any tab.
Once connected, they behave as if they were wired together.</p>
<p>The wires between link nodes are only displayed when a link node is selected.
If there are any wires to other tabs, a virtual node is shown that can be clicked
