I also had the problem with the broken button on the CP homepage. I was going to comment this section out to just disable that button, but I realized if you go to the extension settings, you can just turn that off (third option from the bottom in version 2.0.1. If you want to spend the time hacking the extension file, it’s lines 552-564. I’m pretty sure you just need to add a div or a span somewhere to get the proper background image, but I could be wrong.
