Hi,

Great observation! We have had this discussion internally as well.

For now, we wanted to have a clear separation in the types of content the user is creating on a canvas, since canvas enables different types of content. And, in some cases, there isn't a 1-1 fallback between a canvas shape definition and an HTML element, e.g., an oval with inner radius.

However, we realize that in a lot of cases users just want elements that look like rectangles, and a DIV with certain styles will suffice. We will work to direct users towards that workflow in such cases.

Thanks, Google Web Designer team

Because you used the "shape" tool and not the "tag" tool.
