How do you do that?

Click on the + sign next to the tabs. Uncheck everything except "Primary" (which you can't uncheck anyway)

You know what's funny? You do that and when you look there are still unread things in there that it pulls from the inbox. Once you dispose of them in the inbox, they do disappear, though.

There's actually a number of different inbox layouts available in Settings.
