Yes, seems so. My logic goes like this: Additionally, you'd need to filter through the links in the preview, since beforeunload gets fired if the page gets unloaded, not closed. I could do the coding myself, but it's hard on a phone.
 * Select the textarea element and store all the text that's inside as a variable.
 * On beforeunload, set another variable with all the text that's currently in the textarea.
 * Compare both variables; use .trim if needed.
 * If both are equal, close the window.
 * If not, throw a .confirm and follow accordingly.
