Many of our users have emailed us and said that they're tired of seeing the same topics they have already seen. They simply forget that they visited a topic, only to go over it again the next day. I've received suggestions of a "new listings" filter, even though we already have this feature implemented.
By click the highlighted button, you will instantly see all new topics from the past few days that you haven't seen yet.
These topics are also marked "new," as seen in the image below.
These "new" tags are only added to listings while you were gone, and they disappear after a while, even if you don't enter a particular listing.
If you have any questions, feel free to ask.
