First off, let me say that I think this is a great plugin but the latest release installs menu items for CloudFlare, a third party commercial service. Personally, I think it's a little presumptuous of the developers to think that my business (or my clients) would like to see an advertisement for CloudFlare at the top of our screens consistently throughout our WordPress experience.
Why would this bother me? This morning, I was awaken at 6 by a client who was in a panic that CloudFlare had hacked their website. They suddenly saw a new commercial link on their admin and though somehow they'd been compromised.
I've disabled the admin menu on my sites by disabling the CloudFlare option in W3 Total Cache but the two hours it took to do this on 50 sites could have been easily avoided in the plugin author had appreciated turning on new commercial features should be a new option, not the result of a common behaviour such as turning on site caching.
