Thanks for the feedback, guys. To be fair I haven't seen anybody mention that the article is too long, so thinking about it some more, it makes sense to leave it as is. My initial thought was to split the two different Tutorial portions of this article, but that's not really necessary I admit.
I was considering taking photos of the M3's screen (or perhaps the editor) for some sections because, in general, seeing an example could be easier to grasp for some than reading the text alone. In other articles here, I've put the images within a collapsible block to make the article "appear" cleaner and smaller.
A real pity that Shannon disappeared. He was doing a brilliant job on the wiki and helping people learn about KARMA — I've used the wiki extensively along with the House 101 vids, both have been a huge help. Anyway, I do hope Shannon is OK.
