Close window dialog box?
Would it be possible for Duolingo to get a close window dialog box during lessons? Y'know those boxes that pop up saying "Are you sure you want to navigate away from this page?" or something akin to this.
It's a tiny change, but it would help prevent those times where you accidentally close a tab/window and lose your progress. It has happened to me a couple of times, and usually on the last couple of questions in a lesson. ¬_¬
Oh please, oh please, oh please please please add this. I have accidentally ended so many lessons! Usually by going to a discussion on a question and then, instead of closing the discussion box, cursoring over to click on the "Home" tab instead. Poof! Progress erased!! And I have to start over. I dont know how to cuss yet in Spanish or I would be doing it.
