This extension is really excellent. I had to get used to the new interface, but I now think it works better than the old one.

However, there should be a way to get rid of the animation of the heart next to the donation button. Not even donating gets rid of the animation, currently.

I think I would rate this a 4 if that was the only issue.

But the developer also includes a "bad finger" icon and disables the extension if you try to get rid of the heart with CSS.

That merits one star.
