Notification after time limit

[Koushikphy]

Presently this extension shows notification on crossing a given time limit, like, if I set 1 hour for youtube, then it shows notification on 1hr, 2hr, 3hr etc. Instead of this can we have a feature where it shows notification every, say, 5 min when you cross the limit. For example, it should shows notification on 1hr, 1hr5min, 1hr10min, 1hr15min etc. This is more intuitive than showing notification every 1hr, when you are trying to curb down site usage.
