Hey Steve,
That is good to know. Never used it.
So Gregorius could register a auto-layout action via a plugin, so we can call it that way. And if he wants to do auto-layout by injecting a message, he can simply do that with a function node (by executing that action via Js code). Or if he wants he can build a custom node that is dedicated to executing actions, e.g. that he can select an action from his config screen perhaps...
@gregorius: Perhaps if you create a new discussion about auto layouting, you might get some more feedback compared to a discussion about Noisecraft
