Rated 3 out of 5 stars

Needs to be moveable using the Customize menu. Otherwise it's not very useful.

This review is for a previous version of the add-on (1.1.1-signed.1-signed). 

I'm aware of this, but I have no time to implement it. However, if you want to contribute to the project, I would be more than happy. The project is hosted on GitHub https://github.com/pstadler/ff-pagerank-client
