The game's talent icons and the skill to learn each recipe

Small details players asked for, on the site:

• Talent calculator: each of the 466 talents shows its icon from the game, the one Forever gives it (© Blizzard Entertainment), grey while locked, gold when maxed, with arrows between prerequisites as in the game.
• Professions: the skill to learn each recipe, in orange before yellow, green and grey, and where it comes from: given with the profession, a recipe item, or the trainer (380 trainer recipes take their Classic level, since the beta files have no trainer lists). See Blacksmithing.
