I currently have a single button that triggers the actual configuration (from the 'format' port). Is there some way to trigger the reconfiguration some other way?

Not that I know of.  We could consider adding to buttons in the module info panel to allow this.  We currently have "Configure" and "Documentation" there.

With this example, I see another potential issue where a user could push data into the "format" port during an execution that is different than the current configuration which might cause interesting issues.  Should we differentiate between computational and configuration parameters so this does not happen?  It also might make sense to keep the format entry in the configuration widget and not in the normal ports panel.  A similar case here is the "source" port for PythonSource.
