It would be nice to have an alarm that requires a task to stop it. My idea for a task is to press the buttons in a random order every time the alarm goes off. This can be done by having 1, 2, 3 and 4 next to the buttons, and press them in order. Or have a 4 digit number shown on screen that contains numbers that are defined by the buttons. IE, the watch face can look something like this - if formatting allows:
4 1
2 3
And it changes the order every time.
A nice bonus would be to let you display anything as an alarm message. Such as "Breakfast time" or "Dentist".
The reason for this is that I tend to instantly turn off my alarms with muscle memory, and sometimes I don't even notice they they've gone off. And sometimes I've forgotten what the alarm was for.
