I am a long time user of the The Form Letter Machine.   In my experience, the File-> "save current Variable Setting as .." command is used so frequently that this operation should ALSO be made more easily accessible than just through the File menu ribbon. For, example, I suggest a simple save data "icon" on the menu ribbon to the right of Help would be more convenient.  Once a user works out their tree of check box options, the File-> "save Configuration Tree as..." command is much less frequently used and can stay where it is in the File menu.  The form letter machine is a great utility for those who learn how to use it.
