Topic lists are sorted by latest activity by default. So, Topics with recent activity show up on top. If you want to see topics with oldest activity at the top, you can use this
then you’ll get an activity-based topic list that is in ascending order, in other words, old topics show up at the top.
You can do the same for the views and replies columns. Beyond that, you would need to use the search icon in the header.
