I have just gone through the "Getting Started with Syntax" paper from the doc page on the website. I must say its really helpful. My next thought was how to turn it into a user tool, but that's an aside.
I was looking at the beginning of Matthew and I noticed that in the syntax diagram it appears that the top level N (independent clause) appears to cover the entire sentence constituted by verses 1:2-1:6. But when I rollover the N in the syntax diagram only verse 1:4 is highlighted.
Is this a bug or is there some reason for it ?
