5.x-1.3 has contradictory settings

The addition of the "Send notifications during this hour" box makes nonsense of the "Send notifications every" box settings, if you wish to make the frequency more often than once per 24 hours. They only get sent out once per 24 hours.

Also, on my system, the list of notifications (NOT noticatians!) is growing every day as the old ones never get cleared.

If you want to make significant changes to a minor revision, please draw attention to it in the documentation. I'm going back to earlier versions until I stop using this.
