Rated 3 out of 5 stars

It doesn't calculate wanted position correctly:
Wheel up once. While it still scrolls up in animation wheel down. So you moved +128 px and then -128. You should finish at start position.
But instead scrolling imediatelly stops when wheel up at eg. 79...

IT IS VERY ANNOYING AT FAST WHEEL SCROLLING.

This review is for a previous version of the add-on (2.0.10).
