I would love to see the CC Settings > Custom Code section expanded to work more like the Code Snippets plugin, with PHP support, where I can run these snippets on both the backend and/or frontend. Basically allowing us to use the Custom Code section for more than just injecting code in the header, body, and footer.
For example, if I want to add custom fields to User Profiles or add new user roles, I’d love to be able to use this Custom Code section as a way to do this instead of relying on another plugin.
