Scaladin and Portlet Modes

Is there any sample code for using Scaladin and handling Portlet modes other than view (ie: edit and help)?

There seem to be numerous ways one could handle this via subclassing, but what would the most straight-forward way be for a user of Scaladin 3.0-SNAPSHOT on Vaadin 7.0.7?

Also, are there any plans to make this support a standard feature of Scaladin, such as allowing portlet.xml to specify other UIs for the edit and help modes, along with the current one for the default view mode?

Thank you.
