Semantic HTML output

I’m just taking a look around AppGyver and created a quick page with a heading and a text input.

The generated code I see in the preview uses <div> tags where I would expect to see a <h1> and a <label>.

I would also expect the <label> to have a for attribute to match the (missing) id attribute on the <input>.

Is there any way I can configure the builder to output semantically correct HTML?

So far this is looking like it will completely fail Accessibility testing for WCAG 2.1 Level A.
