Things to try

• Every boss and all of its loot is on one page, in kill order: just scroll. Close all folds the bosses down to a row of loot icons each; click a boss to fold or open it.
• The left column is what to sort out before you go: requirements, entrance, and quests. Click a quest for its detail.
• Change dungeon with the box at the top left: Blackmaw Hold, Blackrock Depths (Keys), Onyxia's Lair.
• Map and Keys are beside Run order, top right of the boss list. Click a map pin to jump to that boss.
• Click the star on a loot row, then open Favourites. Type in the search box: "smite", "cape", "black".
• Reputation, PvP and Loot Finder are in the title bar.

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.
