When I first tested this I couldn't really tell a difference. (Probably did not have my phone configured correctly).

However, when testing this in conjunction with PR #489, it does make a difference and with the last commit, the snooze screen is properly configured and behaves the way I expect when

• global snooze is set
• an alarm is waiting for acknowledgement
• an alarm is acknowledged or snooze button is tapped with no alarm
  • the scheduledAutoHide works as expected

LGTM
