run app, recorder and alarms

What about emitting an "alarm" event? An app could add an handler for it like

Bangle.on("alarm", (important) => {
   // save state?

   var ret = ?

  // ret = 1: exit app and show the alarm
  // ret = 2: remain in the app and show a blinking icon in widget bar 
  // ret = 0: ignore the alarm

   return ret; 
});

Bangle.on("afterAlarm", () => restore..)

Could be an idea?
