I create a lot of themes for NationBuilder users. About a month or two after creating a site, many of them come back at me to add in a Google Tracking Pixel (or some other third-party tracking code). To add this code to the site, I need to add into the theme files. It would be awesome of NationBuilder had a panel in the CRM, accessible to the NationBuilder user, in which they could insert some plain-html that would be inserted into the global template. This would allow them to add code without having to touch theme files like layout.html.
