Great, but... Rated 3 out of 5 stars

I don't know why you would limit the application of this extension to reading speeds. I was so excited to find this addon, then so disappointed when I saw that the scroll speed was limited to a snail's pace.

would it be too much to ask that the scroll speed be allowed to go up to 1000? or 5000? I don't see why it shouldn't be.

And what about auto scrolling tabs on a tab by tab basis instead on only the active tab? (ie selective background tab auto scrolling)

minor tweaks, major benefit :)

Thanks for putting this out there though!
