Hello there !
This is more of an OS feature request but I hope it reaches a Panic employee or some community members that agree with me.
I live in Europe and when the Catalog is updated it sometimes happen late in the night for me.
I suggest that after 10PM the notifications stop triggering the LED automatically and that until 7 or 8AM the morning. This could be based on the device time.
Thanks for reading my little request 
!
