You can navigate a graph just fine if you set up flows to iterate through it, just like state machines (there are a few patterns to do that in Node-RED with branching and iteration). It’s perfectly possible.

However, there is something you mention that I think is important - dashboard 2 is still missing critical functionality—for instance, I cannot set it up as the “/“ (homepage) URL in an instance (there’s a lingering bug for that for around a year now) and it is still far from being as well integrated as the original.
