As far as I can tell. this is not currently available. But if it is please speak up.
My father has dexterity issues and too often breaks the layout I have set up.
I know there is an option to save and load layouts, but what I am looking for is an option to lock the layout so it can not be changed. Alternatively provide an option to force load a user defined layout at start up, this would allow for closing the program and restarting, but not saving the broken layout.
