Whenever you open a post in Mathstack, you can not know how many answer that post has got. To know you need to scroll down to the end of the post. In general when I see a post I how long is the scroll bar, to predict if the question has got an answer or not. But sometimes OP post very long question, so this prediction does not work every time(Although it is a prediction!).
My suggestion is in the right top side where stat of the post shows(i.e. asked and viewed part), another bar where you can see how many answer has been given and any answer accepted or not.
I suggest this because when you refresh new question page you do not expect to open every single at the same time. You open a post, you see the problem, you are interested, you scroll down, otherwise, go for next post. Meanwhile people may have answer your next favourite post. When you open it, you see that it has been answered by someone already. If the post is very long sometimes reading the whole question, you see that 9 or 10 answers has been posted. So to avoid that you need to remember everytime scroll down first.
This is just a suggestion. Just adding one bar would make things more simple and easy to use too. That's all.
