Support for "Repeats from Completion Date"
Is your feature request related to a problem? Please describe. I use Tasks.org on Android and sync via CalDAV to Planify. For recurring tasks Tasks.org has a per-task setting so that tasks "Repeats from Completion Date" rather than "Repeats from Due Date".
For example a task is recurring every 3 days but is currently 2 weeks overdue, and it has "Repeats from Completion Date". On Tasks.org if I complete this task it will then be next due 3 days into the future. On Planify however it'll be now due 11 days ago.
Describe the solution you'd like If tasks have "Repeat from Completion Date" enabled then use that to set the due date for the recurring task.

For things like haircuts or watering plants, it makes sense to plan the next time based on when you last did it.
