This isn't exactly the same, but there's a "New Discussion" filter extension. It displays only discussions with unread comments. But it shows discussions from all categories.
I don't see the tab you're talking about. Maybe it's a specific template. You mean on this kind of page, unread topics for each category? Or the "categories" tab between "discussions" and "search"?
Yes, in there I would like a unread post count. I plan on removing the discussions tab and putting a front page of some other type. But I want my users to be able to look only in the categories they want and need too.
[-Stash-] posted this this in another thread too """ From the discussions page: <li id="Discussion_5577" class="Discussion Read NoNewComments Category_13"> <li id="Discussion_6748" class="Discussion Unread NewComments Category_10 Alternate"> From the categories page: <li id="Category_10" class="Category UnblockedCategory FirstCategory Category_10"> <li id="Category_7" class="Category UnblockedCategory Category_7 Alternate"> Seems we're missing "Read" and "Unread" on the categories - but you can certainly have the alternating colours already :)
Perhaps we could add the Read/Unread thing to the list of wishes for the next release of Vanilla? """
Copying the "Read NoNewComments" into the categories ones wouldn't work right?
