Show unread posts since ever

[chadon]

I am the new administrator of a forum with many boards, sub boards and sub sub boards and the members complain about problems finding unread posts because of the expiration time of the unread posts since last visit function. Is there a custom link available to view all posts still marked with the "new" icon?
phpBB and other softwares offer such feature and if it's not possible, it doesn't seem too complicated to implement this on SMF as there must be a field in the database saying if a post is new or not.
I have been searching the forum and the mods and didn't find anything related to this. I hope someone can help

Never mind, I found it. In the show unread posts since last visit page there is a link at the bottom saying All Unread Topics
