I'm with @tbd on this one. @neauoire You absolutely should think about it. This video explained to me a lot about Orca. I'm a "visualiser" (monkey see monkey do) and I learn faster from that kind of material. She is good at it I must admit and her voice also plays a role because you can feel that joy when she's playing with it but it's always good to know how the person that actually created this software thinks. Could work even better if it was you.
