I’ve enabled two new beta features recently. One allows custom sections to be added to the sidebar navigation.
The other feature is one many of you might find useful: It combines the Unread and New tabs into a single New tab. Basically, it behaves like the current Unseen tab, but it only shows topics you’re actively tracking/watching where as Unseen will show any topic that has had a least one post since the date your account was created.
To enable these features you will need to join the Beta Testers group.
