Well for one, I'm assuming the frontend is all javascript? Am I dependent on a 3rd party service? Are there some examples of how it looks / behaves on the frontend? Is it stable? Is that form submission code adding rows to the spreadsheet? Does it depend on the spreadsheet being a certain format? What about multiple tabs? Does it need to oauth a google account? So on and so forth

I've been trying to figure out how to sort based on row value...
