Sorry if this has been suggested before! :')

Maybe add notifications for when observed auction near their end?
Like, get a new game message when an observed auction is around half an hour from being over (possibly with the function of turning it off in the settings, for people who are bothered by it?)

I realize you could just set an alarm, but having the game itself notify you seems like a neat feature (+ I... honestly forget to set my alarm more often than not haha,,)
