@dave , at some point today or sometime soon, if you have some time, may I respectfully request that the end of the YouTube video be changed so that the seeming dismissal of our swap here doesn't get viewed in that video for all posterity?
I don't think (or hope it didn't, anyway) come across quite the way you intended at the end, but if you re-watch the tail end, I think you might see what I saw and why I'm a little concerned.
Did anyone else watch the tutorial, and did you feel likewise?
