I don't know...I disabled the new tabs actually. Mainly because I HATE that some of my emails are hidden behind other tabs. I personally love how well Gmail implemented the "important" tags, and I use four inboxes one page: "Important and Unread", "(Other) Unread", "Starred", and "Everything else" (in the inbox). This configuration most importantly lets Gmail intelligently decide mail that's important and not, without me having to re-train Google.
