ATTENTION: You must name this file before you can save it. Place the file name in the filename input next to the save button.
ALSO: It is recommended that instead of using this "create a new page option" you should make your own template. Create a template file such as "html_template.html" and click to edit that file. You can then create your page with your own template and save it as any file name. For instance, if you use certain scripts, style sheets or meta tags in all of your pages you may want to create a template so you don't have to add those each time you create a page.
