Very annoying to download, and after installing with most of its features, site breaks down. It was conflicting with other plugins, but I still didnt get anything out of it..

We changed places of some of the options in the General and Advanced tabs, and put a «be careful» warning on top of the Advanced, CDN and Google Analytics tabs. We also updated the CSS, and added a sidebar which has some speed test links that could turn into speed test widgets in the future!
