Good features Rated 2 out of 5 stars

I can't give it a 1-star, for how good it is... but I tell you, making a pop-up message about coupons or whatever whenever I try to close the changelog? That'll cost you a good rating. No matter how good the product is, don't ever pull a stunt like that.

This review is for a previous version of the add-on (4.10).
