Chrome Dev Hopper per Dean Sofer

After configuring your various Projects and their assorted Environment urls in the options page, whenever you open a page that matches a project, the extension will change color and show how many environments are found. When you click on the extension, it will show a popup allowing you to select one of the other environments. All the parts of the URL are preserved when changing environments based on your matching pattern which supports regular expression. If you click on the extension when no matches are found it will take you to the options page where you can define more environments and projects.
