Make a quick-glance way to tell if you've answered a question or not
It would be great to be able to glance at the list of questions and have a symbol or icon show up on the questions you've already responded to (similar to the Best Answer ribbon). This would make it easier on subsequent visits to go through and respond to things you hadn't yet, making it less likely that you miss questions.
That's a great idea! It would be relatively simple to implement, too. We'll put it in queue with these other suggestions for improvements to the site. Thanks!
