There are 2 things you can get from that website. One is a UI thing and the other is a just a profiler like thottbot. I had both originally but I actually didn't need it because most of what it did was already in cosmos. I took out the UI from my addon folder and I am only using the profiler. It works the same way the cosmos thing did. You run it and then you can configure it to either start wow for you or to run the cosmos.exe or whatever.
