    Just used your Amazon link and put a couple of those plugs in my cart. I'll play with those next week. Have you thought about doing one of your great beginner videos for YAML...I'm struggling with it and I know I got code bloat. None of the other videos I've seen are simple enough for me to follow or at least get the basic idea of the template.
