Chrome's path: This is used to launch the browser usually when changing a theme. Theme Path: This is the path I mentioned above, is where the new theme will be copied to, in case existed (which is for sure) it will be overwritten only if Chrome is not using it or any other program. Project Path: Just in case you want a special directory where all your theme projects lies, then this could be done here. However, it's not mandatory to save your projects in that directory, you can use any other location when saving your project. Image Editor: This tool, needs an external image editor. So you can use your favorite editor with it. Finally, save the changes to remember and not doing this again. Notice that if you are upgrading your browser version, Theme Path MUST be updated too. 3.
