Just an FYI...
There's an extender in SMW for the TSW-x70 panels called Button toolbar.
It allows you to show/hide the toolbar and turn each of the 5 buttons on or off.
It also allows you to place the toolbar on either of the 4 sides of the panel.
The one thing I can't remember is if you can completely hide the TB lip (make it inactive). You may need to use the console commands that you mentioned for this...
