This means there will be one point in time where we need to switch the main window from JFrame to Stage and immediately change every other window in the app from JDialog to Stage (because JDialog does not accept a Stage owner). That does not sound like a good option to me, for non-trivial applications.

I intend to pursue this by creating some helper methods to show a dialog containing a single Parent node.  Depending on the parent object for the dialog it would automatically wrap the node in a JFXPanel and use a JDialog, or use a Stage.  That way I keep the ugly stuff in one place and don't have to revisit all those dialogs.

Things would be better if there was an option to use the "Swing embedded in FX" model because then we could slowly push out Swing top down. But that's not how it works now.

It's nice to know that I am not alone.
