Feature Request: Brentilda's Hints

I'd like to have the list of hints the player has heard from Brentilda available in a submenu from the pause screen. I think it should only be available in Gruntilda's Lair (Furnace Fun is optional).

Start by locating the pause screen implementation and the code that records or displays Brentilda's hints. Trace how the current game area is identified, then determine how the hint submenu should be limited to Gruntilda's Lair, with Furnace Fun as an optional case. Done means previously heard hints are accessible from pause in the specified areas.
