Pretty good, but I'm not going to keep using it. I prefer the icon from version 1.3, but the about:cheevos page has stopped working in that version. The about:cheevos page works in later versions, but the new icon is kind of ugly, in my opinion.
I have to deduct a star because our home page with the list of achievements should have images of our badges so we can show them off. It seems like there's a big spot into which they would fit perfectly, but it's just blank.
