Daily Challenge Timer Alert
After a few times where I timed out on a Daily Challenge location because I was too busy scanning the map to notice time was running down, I wish there was some sort of audible notice that I was running out of time. Ten second countdown, a bell at 30 seconds, something. Maybe enabled via a checkbox next to the timer, since I'm assuming some people won't want any sound when playing.
it's very frustrating to forget to make a guess and not have a reminder when time runs out.
