Great tutorials! I wonder if it's possible to fix the "Autoplay next video" order in Vimeo? The main list of tutorials appears to be organized fairly well but the Vimeo autoplay order is random or seems that way. I like to get on my exercise bike and run through these videos just to get an idea of what's available in Photos. (I'll probably have to watch them again, maybe more than once, when I really want to use something, but this is a great way to get an overview.)
