I'm going to second this-- ironically enough, the Mission Power Level thing was one of the exact issues I'd had in mind too, as I'd been trying to explain how the individual missions worked to someone the other day and couldn't for the life of me find the page with the Power Levels on them.

I think a lot of them could be condensed into fewer pages with more information on them (and links at the top, of course, like how the Nitpicker's Guide is set up) just to make it easier for people to go through and find things.

I'll also throw in an offer to help with that if it's needed!
