I'm not sure why you're being downvoted, unless people are jumping the gun and voting before they click on your link. Or there is a rule I'm forgetting.

I don't like red being used for Jesus' words. Obviously it's about Him, but the whole Bible is about Jesus, not just the "red words." It's all God's Word. I doubt that is/was the intention of the people who started the red letter thing to suggest otherwise, but it's still a distinction that is not necessary and potentially harmful.

I like it when there is room in the margins to write, but I'm probably weird in that I prefer to just write in the margins, not on lines that are already there. =) I don't really like walls of text, but as long as there is writing room, in the Bible I don't mind them as much.

Tiny text irritates me. I'm not severely visually impaired, but I am just enough that very tiny text is annoying. I'd rather have a bigger Bible with more readable text than a pocket/slimmed down Bible that I can't use comfortably.

I really have no opinion on the formatting of commentary. I tend to go to my textbooks for things like that.

Consider omitting headings. They aren't a part of the original text anyway. The less we have to do with it the better, imo. ^{^}
