Rated 4 out of 5 stars
The mechanism of this addon is not the same as the one used by AutoPager, so it is unfair to compare them directly.
As a newly developed addon, it is acceptable that it faces some limitation.
But it can also outperform AutoPager in some special cases. (Tested by using the bookmarklet provided in the support web page)
Anyway, keep it up. A good start. It has huge potential.
