I’d like to request that the in-app timer have the option to keep the screen awake, either by default if the screen is on Beeminder with the in-app timer running (preferred!) or as a user-configured setting (but why complicate matters? you can always override by navigating away from the app or manually turning off your screen).
Looking up and seeing the timer counting is a great way to stay on track AND make sure you stop the timer when you finish.
I’m on iOS, if it makes a difference.
