Reminder notification does not appear

[rancidfrog]

I am not getting reminders for subjects.

Also, is it possible to select more specific time for notification for subjects, currently it is limited:

You seem to be using different functions for interval calculations. As each reminder uses different times.
A.

B.

C.

Having one custimizable format will simplify code and give users more flexibility.
