After all the great comments and suggestions from the last update and talking with Matthew Paul Thomas, my student Tomé Vardasca, has been redesigning the UI to be more new-user (and old-user for that matter) friendly as well as adding new functionality.

In Advanced mode you can also access a Preferences window for the individual menu items:
