Currently, if timer remains unacknowledged after expiration, every 30 seconds we hear the timer alarm sound replay. This is good.
Even better: have skill settings for up to N re-notifications (with reasonable default of say, 100), and have escalated notifications options include: increase volume and replay sound, or mycroft speak "Your attention, please: the timer set for X minutes has expired.", and lastly send SMS message notification with text of spoken notification.
