request: please add a feature for a constant low vibrate/silent hum/light indicators during the alarm to show the alarm is active. this should continue for the duration of the alarm between the stimuli events.

it seems I had a faulty device that was doing this and I preferred it. i now have a replacement and found our it should have done that. bur it is now difficult to tell when the alarm has actually stopped.

when it used to hum, I could tell the alarm was on between stimuli bit now I find it difficult to tell if I have completed my jumping jacks or not,
