If twine supports theming the text a bit, a few of the backgrounds have colors that conflict with the text color and are illegible without highlighting. Perhaps a text shadow could be added or a blurred backdrop? This applies to Firefox, at least.

Yeah, you can do it, and I've already done it with a few passages. I really didn't want to because I didn't like the look of a literal block of text taking up the screen, but I think I'll just bite the bullet and fix it in the next update if I can't find a better solution that works on all platforms.
