Ah, I remember getting into this on another forum. I requested it and everyone said, "Oh no, we don't need that. I just use the [method not available to me, but nobody cared] system." Well, I don't have a home key that takes me to the top of the page, and it's a really handy end-user-friendly feature that (so far as I know) doesn't slow down the system. It could be a tiny up arrow to the left of Post Reply or something, it doesn't have to hog a lot of space.
It's the first thing I'll add myself, if it's not already there.
(And, I have to scroll down to get to the bottom-bar top link so.... what's the point of that.)
