If you use the "new posts" feature, you might have noticed that they no longer reset on their own. It used to reset at 15 minutes of inactivity which, in my life of constant interruption, made the feature quite unuseful. However, you can still manually reset your "new posts" at any time by clicking one of the blue dots on the home page. Why does this little blue dot control such things? ... I have no idea, I didn't write the software, but it does what it does.
I hope this tidbit is useful to someone.
