And yes, though Google Forms already exists, I think that having the form write directly to Google Sheets can be useful for some people who might want to do something with that data in their Google Sheet (create charts/graphs or calculate stuff with the data, etc.)

I also plan to add pre-defined layouts to the form builder which people can choose from and also more HTML/CSS (and potentially JS functionality) that people can integrate into their form without having to write code, which I don't believe is something Google Forms offers
