Can I add to functions to the library? To add addButton()

[StudioRATATA]

Hey all,

Is there a way to add custom code to the library? I've added the following code to QSGui() and that works perfectly. Now, I don't want to hard code it in the library itself. Is there a way to to append to the library?

       this.addButton = function(name, callback) {
            qs.addButton( name, callback );
        };

Or even to add in this line in the new version?
