Hello All,
We have just added documentation of the SimpleModifier on to the web site. Please accept our apologies for the delay. You can view it at:
[Link: harmonyremote.tzo.com]The link is accessible from the 'Advanced' page.
Big Picture: The Simple Modifier allows you to make pretty much any change to your configuration. For example, you can add new menu systems, add button bindings, add menu items to existing menus, or rename menu items. To give you an idea, the 'System Options' menu on your harmony (including the full screen graphical icon) is created using a SimpleModifier, and you can view the XML for it to see an example.
Enjoy,
The Harmony Remote Team.
