Things to try

• Open The Deadmines, click pins and boss faces, switch the floor, then the kill count beside a boss's name.
• Switch to Quests above the map and click a quest. Show boss jumps back to the map.
• Click the star on a loot row, then open Favourites.
• Type in the search box: "smite", "cape", "black", "dawn".
• Open Blackmaw Hold (a new dungeon), Blackrock Depths (Keys) and Onyxia's Lair (a raid).
• Loot Finder: pick Two-Hand and Up to Your Level. Reputation: open Argent Dawn.

Only those four dungeons and Argent Dawn are filled in. Buttons that would do something in the game say what, in a note at the bottom of the screen. Player state and some numbers are sample values.
