...take me to the first new reply since the last time I had visited the thread.

If that is too much asked, at least take me to the last page if I have visited the thread before.

Also, it would be nice if the forum would show how many new posts have been added since my last visit to the thread. It would show in brackets beside the total number of posts in said thread, like this for example: 84(6). This would mean that there are 84 total posts in the thread, 6 of which have been added since my last visit (so when I last clicked on the thread, there were 78 posts total, and six new have been added since then).
