A ‘spoilers’ option that toggles on certain interface features that assume a player is spoiled. Defaults to off. An example of such a feature is FIQHack’s automatic identification of a wand of teleportation when the player makes an engraving vanish with it and has already identified the other wands that do so.

Implement “spoiler novels”, cheap books like 3.6 novels that contain spoilers. (Not described in what form the spoilers would be. Several true rumors?)
