How about the "scrolling guides" when you're zoomed? Not sure if there's a proper name for that, but with Opera when I zoomed and the text reflowed, it would lock me to vertical scrolling only as long as I don't wiggle too far horizontally. Easily my favourite thing about it.

also not in as far as I can see. I hope that gets added again in the future, together with the reflow.
