There doesn't appear to be a way to switch back to the "Lite Editor" or whatever it might be called after opting in to the "Advanced Editor".
I also can't see what difference the advanced editor makes for the Layer Editor.
That said, this is an absolutely excellent plugin you've got here. Very straight forward to use, thanks a lot! I honestly think you should read up on commercial plugin development and make the jump. I'd rather pay for a commercial, white-label plugin than donate, as would my clients.
