Count hours instead of shifts

[ferdymercury]

I wonder if it were possible to have a 'shift counting modus' where the countdown is done based on the total number of hours rather than counting number of shifts.

For example, we might have someone who worked 0.5h one day, then 3.5h another day.
In general, a cooperator should work 4 hours every countdown period (let's say monthly).

So... in that case, the plugin should sum the total number of hours, and subtract a value equals workedHours/4h
so, if someone is missing 1h this month, it will subtract just 0.25.
