Yeah finally a useful extension.
But: There is one bug! In "Latest" or "Newest" filter, it show current post in the list if we are in newest topic.
I mean it should exclude or hide the topic that we are already reading it. If i enter the latest topic in my forum, i can see that topic in the more topic's list, it should be excluded.
I hope you fix this
Another suggestion: is "Adding random topic list" for "Filter by" option so we can show random topics.
