Feedback → [request] Confirmation on page nav if text is filled

Numerous posts of mind have been lost from the iPhone by the page loading something else on this site while I was typing. I think because the abnormally small iPhone screen and large fingers, sometimes they must be hitting something that causes a page navigation to take place. It's very frustrating because hitting the back button results in a blank post or a thread where you have to hit reply again.

Could you put script on the page that detected if any text was entered into a form field to prompt a confirmation on page load?

Either that or integrate with Tapatalk mobile app?
