It would be nice if there was a button option in the website builder where we could switch to full code view/custom code mode in order to fully write our own HTML from scratch. I know there is a code element, but it isn't good enough. There should be a full code editor available so that agencies can create sites for clients or as templates using proper semantic HTML 5 tags (header, main, section, footer tags) and also not having it wrap elements in unnecessary nested divs.
