[Feature] Alarm: Show time remaining
Hi,
After setting an alarm, it would be really useful to know how much time is left until it rings. I often set an alarm when I'm cooking, for let's say 30 minutes, but I have to do the math in my head and, after I set the alarm, I still have to do the math again just to make sure I set the alarm for 30 minutes. If we had the time remaining, I would have the confirmation that I got the time right and I wouldn't have to do the math in my head.
Goes well with the following suggestion: #259
