The thing is, I'd be glad of this sort of thing in-game which could be sought out at need (go to Elminster) or turned on/off (map guide arrow).

I'm about 3 personal projects and 2 side jobs and 1 computer generation too far behind to play BG3 --- positive reports such as yours make me regret that, but I also worry about disturbing my pleasant memories of resolving a crisis and ensuring the best endings for my various companions....
