This forum has destroyed my productivity... but shame on me. So, I created a graphic to show how things might transition.... scale is reasonably good. Hope that it helps some of you to envision what is to come. Flow here is from left to right or counterclockwise. It is just a piggyback of what Disneyhead and others have posted. I am just anal. I hope some find it helpful.
